Materials For LED Optics

Several articles can be found regarding the lifetime of Light Emitting Diode (LED) luminesces, although the primary focus has always been on the lifetime of the LED diode itself. Given that the LED luminesces is a system, it is important to diagnosticate all aspects of the system that can affect or limit lifetime. The LED lighting revolution plastic optics have been made primarily from acrylic (PMMA), polycarbonate or a modified version of either material (for example PMMI). More recently, the market share of silicon-based optical materials have also grown quite well. These silicone resins are suitable for precise molding and can be used for refractive lenses, TIR lenses, reflectors, diffusers and other optical components. Polycarbonate materials are utilized for LED optic and lens applications, especially when heat, flame, or impact resistance is required. Conventional transparent polycarbonate can show signs of hazing and yellowing when they are exposed to intense LED radiation in the 450-550-nm range and long-term direct outdoor sunlight exposure. In order to mitigate the absorption of this intense LED light, LED polycarbonate grades had been developed to extend the optical performance. A UV infusion process has also been described to produce parts that exhibit minor changes in yellowness similar to acrylic after UV exposure.

Most luminesce designers are prosaic with the need to optimize thermal performance evidenced by the large number of articles written on the subject. LED die lifetime has been shown to be driven primarily by junction temperature and to a lesser extent by current density, although the effects of current density and current spreading have been largely overlooked. LED luminaire designers are much less aware, however, of the importance of selecting the proper optical materials for the primary and secondary optics that comprise the luminaire with respect to lifetime degradation due to aging of the optics.

Different parts of a LED lamp require different properties of materials. There are four different product types for the various requirements.

● LED grades - With transparent polycarbonate, it’s possible to efficiently design and manufacture LED parts with complex geometries that would not be producible with glass. OFH LED grades are specially developed for use in lenses and secondary optics. They have an extremely high purity and thus a much better stability against LED light in comparison to standard or optical grades. Yellowness index and haze after long-term illumination with LED light are highly reduced, transmission remains on high levels.

● Diffusion colors - For ambient lighting, materials with high diffusion are smitted that have at the same time a high transmission value. Those two basically opposing properties can be balanced by color formulation experts according to customer needs with special diffusion color recipes. Close collaboration with customer in terms of desired transmission values, wall thickness of the diffusor, half power angle and lighting setup leads to perfect match for almost every customer requirement. Grades with and without UV protection and different viscosities are available in diffusion colors as well as diffuser sheets.

● Highly reflecting materials - Diffuse reflectors can be used for indirect lighting. OFH has developed special grades called RW (reflective white) that have high efficiency in reflecting visible light. Compared to the standard white grades, almost a reflection value up to 95% increased lead to very high brightness. For specular lighting metallization of standard grades is possible.

● Thermally conductive materials - Heat management in LED lamps is of utmost importance. It requires thermally conductive materials. Traditionally, metals are used which limit design possibilities. A thermal conductivity of around 20W/Km is an extremely good value for a thermoplastic material allowing replacing alumina in LED heat sinks.

● Polycarbonates - These are another strong contender that addresses the specific needs of LEDs. The LED-grade materials are designed to tolerate long-term heat exposure, transmit light effectively, and have good clarity. A diffusion additive can also be added to polycarbonates to mitigate glare.

As Optics For Hire continues to explore the opportunities unique to LEDs, the push for higher efficacies will keep introducing new heat-resistant materials and more customized optical solutions. Although the latter has already begun; 3D printing technology is speeding up prototyping and even printing optics to order. Such developments might emphasize solid-state lighting’s importance as a source of not only efficiency but also beautiful and controlled light in future.

What is Optomechanical Design?

Optomechanical design is the key to optical system performances. Satisfying communication between members of the team and awareness of the issues touched on above insures that the optical system actual enclosure is practical, sinewy, and performs to specification. It is a sub-discipline of mechanical engineering where optics such as prisms, lenses, and mirrors are intermixed into mechanical structures like housings, beams, cells, etc. in order to form an optical instrument. The design for a typical optical instrument results basically from the cooperative efforts of a team of designers of lens, optical engineers, and mechanical engineers. They seek and apply the input from experts in concoction, assembly, alignment, and testing as well as from specialists on the light sources, film, detectors, focal plane arrays, electronics, signal processing, and many more that might be used in the instrument.

An optical system functions properly only as when the optics remain within the allowed resilience of the nominal locations, orientations and structural deflections that are caused by the gravity and certain other external forces or by any temperature changes that do not excessively wrench the optical surfaces. Structural designs must be invariable enough to control these effects throughout the operating temperature range. The structure must concuss the optics in such a manner that they do not get damaged or irrevocably moved when exposed to extreme environmental conditions. Temporary deflections of optics and mechanical parts are copacetic during any shock, vibration, or any temperature changes beyond the operating ranges so long as the parts make the cut and come back to their ostensible positions after the exposure.

To minimize the effects of the temperature changes, designers can engineer the structure to be passively ethereal, i.e., insensitive to any changes over full operating temperature range. To maximize performance without excessively tight tolerances on dimensions, one should design a carefully optimized number of mechanical adjustments into the instrument. Secure tolerant budgets after analyzing the sensitivities of eccentricity to component positional errors. Design the structures for maximum possible stiffness within weight and packaging constraints as that tends to reduce the deflections from external forces such as gravity. In addition, also isolate the supported optical components from mechanical resonance effects under vibration conditions.

The best optical system remains useless without an accurate assemblage and alignment. Right and proper engineering means designing for success at this particular step. Although the guidelines are not always intuitive, minimizing the number of adjustments is correct for a fine alignment. Too many adjustments prove too bad to few.

A Guide To Lenses and Optics

“Let there be light” takes on new meaning in the era of LEDs. Light from solid state light sources can be focussed and shaped by optics and lenses, and it is significantly easier to obtain specific colours or adjust the colour of the light. The innovations brought about by LED lighting technology are described in our Lenses and Optics guide.

Optics

The term ‘optics’ refers to components that are used to collect, shape and direct light in order to produce a usable light source with effective light output. Asymmetrical lenses are being used more and more in applications such as street lighting to direct the light beam effectively without generating stray light or glare. There are essentially three types of LED optics:

Primary: attached directly to the LED. Primary optics are usually part of the LED package, with the lenses integrated into the LED package, especially with SMT and high-power devices. This may cause the luminous flux emitted by the LED to have a particular radiation pattern.

Secondary: fitted directly over or around the LED. Secondary optics consist of lenses and reflectors that are fitted on top of the LED to provide the desired form of light output.

Tertiary: external devices. Tertiary optics include a wide variety of optical devices used to diffuse or direct light. A typical example is a light guide.

Lenses and reflectors

Lenses are usually classified as secondary optics and are fitted directly on the LED. They usually produce a light beam with a large optical viewing angle and a circular cross-section. Reflectors are additionally fitted on lenses to improve the bundling and steering of the light beam. This results in highly focussed light, such as a spotlight. High-quality reflectors are characterised by low stray light. In applications such as pocket torches, moveable reflectors can be used to adjust the focus of the light beam.

Light guides

Light guides are external LED lighting technology devices classified as tertiary optics. Their characteristics help optimise the use of LEDs. Light guides are used to diffuse, direct and transport light. LEDs can be switched and modulated very quickly by controlling their operating current. The high modulation rate of LEDs is important for use in optoelectronics and in data transmission using fibre-optic light guides. Fibre optics are usually made from glass, quartz or plastic.

Optical viewing angle and radiant power

The optical viewing angle is one of the key characteristics of LEDs. Incandescent lamps radiate light in all directions, but LEDs emit light in a cone-shaped beam with a specific optical viewing angle. LEDs always illuminate only part of the area around them. Multiple LEDs are necessary for all-round lighting.

Typically, when we think of LED optics, what comes to mind in a plastic lens of some sort used over the LED itself to focus or disperse the light. We need to take a step back and realize the LED itself has a protective casing called the primary optic. The primary optic serves two purposes: to protect and to shape the light output of the diode.

So why aren’t optics used everywhere then? Well there are disadvantages of secondary optics with some of them being pretty significant:

They can be expensive. They typically add between 25%-50% to the cost of each LED.

With few exceptions, they create a harsh transition from bright to dark. In other words, the “edges” of the cone-shaped light pattern can be very distinct. This creates a “flashlight effect”, where everything within the light beam is very bright, and everything just outside the beam is very dark.

They hinder color blending. Since most of us like the actinic effect of all blue lighting, and since most of us prefer a cooler color than the coolest white LED available, we must use a combination of royal blue and white LEDs in our systems. When secondary optics are added, you may see obvious white and blue spots in your tank. This effect can be reduced by reducing the center to center spacing of each LED, so that the cones effectively overlap, but it may still be very apparent as our corals grow towards the top of the tank. Also, our rock formations and corals cast shadows, which may be distractingly blue or white under secondary optics.

We expect the market for LED's to continue to grow and other advanced lighting and we will continue to bring you more quality information on the advances in this promising technology.

LED Lens Manufacturing: How It Benefits People and Organizations

These days, we are seeing more and more people using Light Emitting Diodes or LED optics over other conventional sources of lighting. These lighting components are used everywhere starting from homes to offices, industrial units, on the streets, car parking areas, and more. One of the main reasons for using LEDs is that they are claimed as more energy efficient and can last longer. Moreover, they have some other unique features that make them the right choice for some applications.

Lens manufacturing companies take into consideration some factors when creating various optical components, including product design, size and form factor, directional light emission, instant on at full output, mechanical failure resistance, dimming and control capability, and more. People also prefer to use lighting products that give improved performance at cold temperatures and have an extended lifetime.

How LED is different from other lighting products?

LEDs are semiconductor devices that produce light through electroluminescence. Incandescent and fluorescent emit light via a heated filament and by using a gas discharge while high-intensity discharge (HID) lamps use an electric arc discharge to produce light.

LED lighting products have a minute chip of size 1 square mm made of several layers of semi-conducting material. Your LED packages may contain just one chip or multiple chips usually enclosed in a lens or encapsulant. LEDs are finally mounted on a circuit board and combined into a lighting fixture, closed to an architectural structure, or made to fit the form factor of a traditional lamp.

LED Product Design

Although not all LED products are built in the same way, the basic components often remain the same. For example, there is the chip along with various components that are needed for thermal regulation to produce the desired spectrum, controlling electrical characteristics or creating the appropriate light distribution mode. Usually LEDs are made of silicone lens, have a phosphor plate, transient voltage suppressor, cathode, bond and metal interconnect layers, thermal bed and ceramic substrate.

Size and Form Factor

The small size of LEDs offers the possibility for innovative, low profile, or compact lighting products. If you reduce the depth of a luminaire, you create more space for ducts, conduit, or other building systems. Even the size of the ceiling plenum could be reduced.

Directional Light Emission

Traditional light sources are used to emit light in all directions. However, there are many applications that require light generally in one or two directions. In such cases, light gets wasted. You require using special LED optics to make directional light sources, but they cause light losses. In contrast, LEDs emit light hemispherically, rather than spherically.

Instant on at Full Output

When using fluorescent lamps particularly compact fluorescent lamps, they not always provide full brightness immediately after been switched on. HID lamps can take more time warm up ranging for several minutes. LEDs on the other hand can produce full brightness almost instantly.

Why You Need To Hire The Best Optical Lens Manufacturer?

Not all optical lens manufacturers sell their products directly to the public. Many of them are wholesalers. These manufacturers design a variety of optical components starting from microscopes to digital microscopes, cameras, and more that gives high-quality optical equipment to their clients.

Opticians, educational institutions, laboratories, industries, etc. often need an established lens manufacturing company to get the desired types of lens for use, including retail glasses, contacts, compound, stereoscopic and others.

If you are searching for a professional optical lens manufacturer, you need to pick up the best one from the lot. This is important to make sure the professional meets your exact specifications and needs to create top-quality optical products on time. They must also maintain a consistent quality. Therefore, it is crucial for you to research on the available lens manufacturers before hiring one and committing to a long term business relationship.

A wholesale lens creator may utilize production facilities out of the country, usually in developing countries like Asia, in order to keep the wholesale optical costs as low as possible. Throughout the optical industry, it is a common feature where outsourcing is done to lower down the operational costs.

Before the manufactured products are shipped to company’s warehouse in USA, each product is carefully checked and quality inspected by a professional quality inspector. Only after a well-planned inspection process takes place, the glass products are shipped to their desired locations.

There is a need to carefully inspect each product in order to make sure no faulty component is shipped. Every part and aspect is checked to ensure they are fully complied with written or said specifications. Upon reaching the warehouse in the United States, each instrument should be properly inspected again by a highly trained quality assurance team. These thorough examinations help the client get the best quality optical products and feel most assured that he or she is not cheated on quality.

Quality assurance team consists of only knowledgeable and experienced people who are quick to reject any product that varies even the slightest from the maintained standards of the optical lens manufacturer. With this extra inspection done, the warehouse in the States will always get the absolutely top quality product in each price range.

The most advanced independent labs offer an up-to-date lens manufacturing process that includes anti-reflective coatings. They also use the newest material (silicon hydro gel) for contact lenses since it has higher oxygen permeability.

Professional opticians should look for laboratories specializing in wholesale supply of optical goods. Eye care products need more detailed and dedicated supervision to deliver superior quality lenses to various optical stores.

In naked eyes, all optical lenses look the same. But a well-designed and carefully manufactured lens stands out from the rest providing superior vision and durability.

A good lens manufacturer is one who understands the details of glass structures and carefully monitors the lens engineering processes to create optical goods that are of excellent design and regularity.

You must therefore contact the best company to deliver high-quality optical products only.

Wafer-based Micro Optics Manufacturing, Characterization and Testing

Micro optics is a vital technology for many applications today. The important role of micro-optical components is based on three different levels: miniaturization, high functionality and packaging. Miniaturized systems require micro optics manufacturing for light focusing, light shaping and imaging. In other industries, more precise applications of micro optical components are made.

Previously some alternative technologies including grinding, ultrasonic lapping, diamond drilling and cutting, ion-diffusion, laser ablation, casting, embossing, molding, ion-implanting, etc. have been developed for manufacturing of micro-optics. However, none of these technologies could match with the level of wafer-based manufacturing. Wafer-based manufacturing of micro optics is based on standard technologies from the semiconductor industry like resist coating, lithography, reactive ion etching, deposition, sputtering, and lift-off.

Wafer-optics manufacturing on research-level typically used 100mm wafer technology, whereas industrial manufacturing is typically based on 150mm and 200mm technology respectively. This choice is much related to the cost of owning and operating equipment. Today, the100mm equipment has been phased out by semiconductor industry and since 2004 the 300mm wafer-technology is the standard in semiconductor industry. For lens manufacturing, the best choice would be 200mm technology.

Wafer Cleaning and Photoresist Coating

Wafer-based technology for micro optics manufacturing starts with wet cleaning. Piranha etch, a mixture of sulfuric acid (H2SO4) and hydrogen peroxide (H2O2) is used to remove organic contamination. Additional ultra or mega-sonic cleaning, brush cleaning, high-pressure water jet or plasma cleaning might be used as well.

For manufacturing of diffractive optical elements (DOE), 20nm to several microns of a thin resist layer is spin-coated and patterned by photolithography. You might have to coat additional resist layers on top of the previous layers, if needed. For refractive optical elements (ROE), the required resist layer thickness may range from some microns to more than 100µm layers.

Lithography

Today, micro optics industry uses immersion lithography steppers to print structures down to some 22 nanometers on 300mm wafers in mass-production. Compared to semiconductor industry, the lithography requirements for micro-optics are much more relaxed.

Due to a very limited depth-of-focus, projection lithography tools are not appropriate for thick resist exposure. So, mask aligners in contact or proximity mode are the preferred lithography tool.

Reactive Ion Etching

Here the resist structures are transferred into the bulk wafer material by plasma ion etching. Wafer processing reactive ion etching process removes atoms from the resist and wafer surface at different etch rates. Surface areas covered by resist structures are protected until the covering resist layer is removed. Typical etch rates range from less than 0.01µm/min to about 1µm/min depending on the ion energy and the reactive etch gases in the plasma chamber.

These well-established technologies allow the manufacturing of almost any shape of micro optical components. You will get the best quality of micro optics depending on your choice of manufacturing equipment and process control. To note, as all processes are standard semiconductor technology, the quality is merely a question of budget and the optimization effort.

However, for micro optics characterization and testing, neither the test equipment from semiconductor industry nor the classical optics manufacturing test equipment is suitable. This lack of suitable test equipment is a major problem for this industry today.

Polycarbonates: The Ideal Choice for LED Lens Manufacturing

About Polycarbonates

Polycarbonates are plastics that are widely used in the chemical industry because of their unique properties such as temperature resistance and excellent optical properties. Usually, in the lighting industry, glass and transparent plastics, especially acrylic resins were used. However, with the evolution of the industry, LED or light-emitting diode has moved from narrower applications to wider commercial and residential use, and there has been an increasing demand in the use of plastics particularly polycarbonate.

Polycarbonate plastics are used for LED lens manufacturing because of their high durability, heat resistance, transparency and high infraction index. Polycarbonate lenses are also thinner than glass lenses and almost unbreakable.

Use of Polycarbonate in Flashlight Lens

Since polycarbonate lenses are unbreakable, they are the ideal choice for making flashlight lenses. Flashlights have thin lenses that are less prone to damage. This is the reason why polycarbonates are more expensive than glass and other types of lenses. Polycarbonate lenses can easily correct poor quality of light and hence are used in flashlights so that the quality of light can be improved. They also have scratch resistance coating, which prevents them from getting distorted in light omitted by LED flashlight. They can easily be molded and shaped as per the requirements and can be fitted properly in LED optics.

Reasons to choose polycarbonate lenses over glass lenses

There are many advantages of using polycarbonate lenses over glass lenses. Let’s quickly go through them one by one.

Polycarbonate lens are ten times more impact resistant than any other plastic or glass lenses

They provide up to 100% protection from the sun’s harmful UV rays

Polycarbonate is lightweight, and so preferred for manufacturing of eyeglasses, sunglasses, and sports eyewear

Glass lenses can easily break with slightest of force. Polycarbonate lenses are almost unbreakable so risk of damages is less

LED lens manufacturing using polycarbonate plastics are more durable and are scratch resistant

They are safe and an affordable alternative to standard plastic and glass eyeglasses

Athletes and those who work in hazardous environments prefer polycarbonate lenses since they are less likely to fracture than plastic or glass lenses

However, there are some significant disadvantages related to polycarbonate lenses, including oxidation or discoloration. You might not be able to notice with your naked eyes, but these polycarbonate lenses are made up of materials which expand when exposed to heat or higher temperatures. This can cause debris, dust and UV rays to enter the lenses over a period of time. Oxidation can also lead to fading and the lens may appear foggy and cloudy over the years. Due to quality degradation, amount of light entering the lenses can also be affected and you may not get the same level of satisfaction you used to get in the initial days of using polycarbonate lens.

Depending upon the needs, you should select the best product for you. However, no product is free from disadvantages and the same applies for LED optics as well. It is however a wise idea to opt for LED flashlights to continue enjoying the high beam of light with better quality.

Learn about the LED Lens Manufacturing Process

Optics design is an integral part within the field of LED light development. LED, the full form of which is Light-Emitting Diode, emits light by electronic excitation rather than heat generation unlike the normal light bulbs. Diodes are electrical valves that allow electrical current to flow in only one direction. Optical engineers produce a variety of LED optics for shops, offices, industrial plants and street lighting.

There are different optics shapes available for selection depending on particular usage, including circular, square and linear. All LED optical products are made of high-quality materials such as PMMA, silicone, and are available with different radiation angles - narrow/broad beam, asymmetrical or combinations.

Design

Desirable optical properties such as color, brightness, and efficiency must be optimized without an unreasonable electrical or physical design. These properties are affected by the size of the diode, the exact semiconductor materials used to make it, the thickness of the diode layers, and the type and amount of impurities used in the semiconductor.

Lens Manufacturing Process

LED optical products are designed after identifying the purpose of use. The designer selects the optical materials, production-compliant optics design, suitable tooling solutions and the appropriate method for manufacturing the final product. Usually, injection-molding method is used by the optical manufacturers.

For LED lens manufacturing, silicone is mostly used as a raw material. LEDs of latest generation, including High Brightness LEDs and COB LEDs, achieve very high temperatures which could put pressure on the conventional polymers such as PMMI, PMMA, and PC. It is because of this that silicone is used to create high-end LED products.

Silicone is an isotropic material that provides LED optics with high flexibility which allows an easy fit as well as a perfect compensation for the construction mechanical tolerances typical of the final application.

Silicone is mostly preferred because of its high temperature resistance, strong heat aging resistance and high chemical resistance as well as ultraviolet (UV) stability, purity, clarity, and stable mechanical properties at a temperature ranging from 40°C to 200°C.

Engineers also use new optical techniques that allow sharpening the extreme angles and elaborate specific geometries developed in order to make the innovative lenses able to achieve a superior optical refractive index, while delivering best optical performance.

LEDs manufactured using silicone considerably reduces the manufacturing process time than lens made of a conventional polymer (PMMA, PMMI or PC). Reduced manufacturing time helps to reduce the production costs and also saves energy. However, it requires a great deal of technical expertise and skill for implementing this procedure. Also, when a lens is considerably large, the transformation process becomes much more complicated. Great care and technical mastery are needed either when the silicone is injected or when the molded part is removed from the mold during the de-molding process.

Injection molding production process forms the basis for manufacturing different optical components including LED. Most optical products are manufactured using either poly (methyl) methacrylate (PMMA) or polycarbonate (PC). An injection molding machine, raw material, and a mold is used for injection molding. The raw materials are melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part.

After the product is manufactured, it is sent for quality inspection where it goes through rigorous testing to ensure high quality standard is maintained at all times. After assuming the products pass through quality testing, final assembly of the individual pre-tested components are performed using advanced tooling solutions then concludes the process.

How to Choose the Best Lens for Your Glasses?

Our eyeglass frame is important for appearance and comfort purpose; however, your eyeglass lenses should not only be trendy, but they must be comfortable offering correct vision and safety for long-term use.

A common mistake most people make when buying eyeglasses is not spending enough time to enquire about the lens materials, design and lens modeling process.

Eyeglass Lens Materials – Features and Benefits

In earlier days, all eyeglass lenses were made of glass. Although they gave precision, glasses are brittle and heavy to carry. For these reasons, glass lenses are no longer widely used for lens manufacturing.

Thickness of lens depends on its size and frame style. For thinner lenses, choose smaller, round or oval frames.

Plastic Lenses: Lightweight plastic lenses, made of polymer called CR-39 were first introduced in 1947 by the Armorlite Lens Company in California. Because of its light weight, low-cost and outstanding optical qualities, CR-39 plastic is still a widely used material even today!

Polycarbonate Lenses: In early 1970s, Gentex Corporation introduced the first polycarbonate lenses for safety glasses. Polycarbonate is lighter and more impact-resistant than CR-39 plastic, ideal for use in children’s eyewear, safety glasses, and sports eyewear.

Trivex is a newer lightweight eyeglass lens material with similar impact-resistant properties as polycarbonate.

High-index Plastic Lenses: In response to the increasing demand for thinner, lighter eyeglasses, a number of optical manufacturing companies introduced high-index plastic lenses. These lenses are thinner and lighter and have a higher index of refraction.

The index of refraction relatively measures the efficiency of an optical material to refract (bend) light depending on how fast light travels through the material. A lens made of a material with a high refractive index will be thinner than a lens made of a material with a lower refractive index.

Aspheric Design

In addition to choosing a lens material that has a high index of refraction, you should choose an aspheric designed lens. In this lens modeling process, the lens curvature changes gradually from the center of the lens to its edge letting the manufacturers use flatter curves without degrading their optical qualities. Because aspheric lenses are flatter than spherical lens designs, you can have a better appearance and also improved clarity.

Minimum Center Thickness (or Edge Thickness)

The size and shape of your eyeglass frame will also affect the thickness of your lenses, especially if you have a strong prescription. If you choose a smaller, well-centered frame, you can use thinner and light weight lens. Generally, the thinnest lenses are aspheric lenses made of a high-index material.

Why Optics Manufacturers Must Use Color-Corrected Aspheric Lenses?

As far as the design phase of lenses is concerned, one of the critical areas for consideration is minimizing the number of lenses used during optical assembly. Ideally, every lens manufacturing company should use a single lens to reduce multiple aberrations. One of the best types of lenses that can be utilized to achieve this goal is color-corrected aspheric lenses. These lenses reduce both spherical and chromatic aberration making them ideal for a range of applications where quality and accuracy matters.

To note, chromatic aberration occurs in conventional optical lenses when different wavelengths of light focus at different points along the optical axis. The problem is solved by using multiple lenses made of glass that has different directories of refraction into an optical assembly.

However, optics manufacturing companies can use color-corrected aspheric lenses to eliminate chromatic aberration with color-corrected aspheric lenses. The system requires using a few lenses to resolve the issue. Now, many of you might wonder, why the need for reducing the number of lenses in an assembly? Well, the answer lies in the fact that you can considerably reduce the size and weight of the assembly if you use less number of lenses. It simplifies the assembly process resulting in producing imaging lenses that cost much less and outstrip assemblies made of traditional spherical optical constituents.

Knowing Chromatic Aberrations

Optical aberrations are abnormalities not caused by any physical, optical, or mechanical flaws, but they are caused by the lens shape or location of optical elements within a system due to the wave nature of light. There are mainly two types of Chromatic Aberrations - Transverse Chromatic Aberration and Longitudinal Chromatic Aberration.

Transverse Chromatic Aberration occurs when the size of the image changes with wavelength, and Longitudinal Chromatic Aberration happens when different light wavelengths focus at different points along the optical axis because of scattering properties of glass.

Optical designers use different tools to recognize and correct aberrations. These tools often include computer generated spot diagrams and chromatic focal shift comparisons. Spot diagrams represent an assessment of the smallest spot size an optical lens can focus. Chromatic focal shift displays the focal length of an optical lens over different wavelengths.

How to Choose the Best Glass Lens?

It is not the frames of your eyewear that matters but the type of lenses you choose that will go on to make you happy and satisfied for the rest of your life.

Buying glass lenses is not an easy task. In fact, an edition of the Consumer Reports magazine has rightfully said that people are getting more than one option nowadays as far as lenses and coatings are concerned. So, it is quite natural for them to get confused what is worth buying.

In this blog, I have talked about the hype with regard to different types of eyeglass lenses to help you choose lenses and coatings that offer the best features and value to you.

Why you need to choose the right glass lens for your needs?

When buying the frame of your eyeglasses, you need to look into factors such as appearance (how beautiful it looks on you) and on the comfort level. But, when going for shopping of eyeglass lens, you need to consider four factors - appearance, comfort, vision and safety.

A common mistake most people make when buying eyeglasses is not paying attention to the lens materials, designs and coatings. It is essential to see during the imaging lens manufacturing what materials are used to make the lenses. Equally important is coatings applied on the eyewear lens design.

Whether you need single vision lenses to correct shortsightedness or astigmatism, or you need progressive lenses, bifocals or other multifocal lenses to correct presbyopia, the fact holds true for all types of lenses.

Eyeglass Lens - Its Features and Benefits

In earlier times, all eyeglass lenses were made of glass, as men didn’t know the use of plastic or other materials to create eyewear.

Although glass lenses offer excellent vision, they are heavy in weight and can break easily. If glass lenses break by accident, they can cause serious injuries to the eyes leading to even loss of vision completely. For all these reasons, lenses manufacturers started looking for other types of lens materials plastic, polycarbonate etc. and hence today we see glass lens no longer widely used.

In 1947, the Armorlite Lens Company in California, USA introduced the first lightweight plastic eyeglass lenses. As part of lens molding services, plastic polymer called CR-39 was used. It is an abbreviation for “Columbia Resin 39” because it was the 39th preparation of a thermal-cured plastic developed by PPG Industries in the early 1940s.

Because of light weight, low cost and outstanding optical qualities, CR-39 plastic remain a popular material for eyeglass lenses even to this day.

In the early 1970s, Gentex Corporation introduced mankind to the first polycarbonate lenses for safety glasses. Later in the 1980s, polycarbonate lenses became increasingly popular.

Polycarbonate is lighter and more impact-resistant than plastic. So, it is a preferred material for children’s eyewear, safety glasses and sports eyewear.

Of late, PPG Industries launched another type of eye glasses called Trivex. It is lightweight and impact-resistant like polycarbonate. A potential visual advantage of Trivex is that it has higher Abbe value.

In the last 20 years, with increasing demand for thinner, lighter eyeglasses, a number of lens manufacturers started using high-index plastic lenses. These lenses are thinner and lighter than CR-39 plastic because they have higher index of refraction and lower specific gravity.

Precision Glass Molding Versus Plastic Optics: Key Features and Benefits

For the production of high quality, accurate lenses, these days we see the increased use of molded plastic optics. In addition of been inexpensive, plastic has higher impact resistance, is light weight, and is easy to configure for multiple applications and systems. However, most of the literature on plastic optics largely ignores the importance of an alternate glass fabrication technology: precision glass molding or PGM. It is a replicative process used for manufacturing of glass optical products eliminating the need of grinding and polishing. In addition to offering the same advantages of plastic molded optics, PGM provides an additional benefit of using glass for complex lens geometries in a more cost-efficient manner. This technology is often not used out of the misconception that glass is more expensive than plastic. You can easily use precision glass molding technique to produce aspheric surfaces, diffractive elements, and various mounting options. Not many of you may know but PGM is in use since the late 1970s. It is one of the most cost-effective solutions for a majority of optical applications.

Material Properties

Whether it is injection molding of plastics or compression molding of glass, all begins with the raw material. If you study the description of illustrative raw materials for molding, you will find that the solution set for glass is significantly larger than that for plastic. There are more than 100 options available for moldable glass, whereas very little options are available for optical plastic. Moreover, moldable glass offers some additional advantages in terms of material properties. Moldable glass offers a better selection of optical criteria, including index of refraction, Abbe number, and optical transmission, and many more to choose from.

Primary injection-molded plastic optics such as COP, PC, and PMMA have optical transmission in the low 80% to high 90% range from 350 to 1200 nm. In case of molded glass, the standard transmission profile is in the high 90% range. Besides, the thermal performance of moldable glass is significantly better than that of moldable plastic.

Moldable glasses have higher service temperatures. PMMA type of moldable plastics has problems with water absorption that can impact the optical performance. Hence before finalizing PMMA moldable plastics for mass manufacturing, you should keep in mind its issues.

The primary reason why many optical lenses manufacturers consider plastic over glass is weight. Plastic is lighter in weight than glass. Plastic optics exhibits at least a 2:1 ratio advantage in possible weight reduction.

However, glass optics is better if you consider environmental durability and scratch resistance. They exceed plastics in these two regions.

Plastic injection molded optics offer additional mounting features or multiple optical surfaces. However, it is also possible to avail additional mounting features from PGM as well! These optical glass lenses will typically have an integral mounting projection. Glass can also be used to manufacture lens arrays, stepped features, diffractive surfaces, and non-cylindrical outer surfaces. Glass can also be precast directly into metal housings with PGM. Overall, PGM is limited when associated to the complex geometries possible from plastic optics, but with time, the ability of PGM to provide such features continues to develop.

Given the limitations of glass, PGM provides a higher-quality standard product than injection-molded plastic optics. This is because of the advantages that PGM provides in terms of better heat resistance, high-quality optics, and greater sturdiness compared to plastic. The molding of glass is easy and less vulnerable to shrinkage, which brings greater consistency in performance and accuracy.

As discussed above, one of the main reasons for choosing plastic in optical lenses manufacturing is because of its low cost. Although tooling costs for injection-molded plastic optics varies greatly, for simple lenses the tooling costs is rather inexpensive.

As far as raw materials are concerned, there is no significant difference between materials. In 2011, the price of optical-grade polycarbonate for injection molding was less than $1.00/kg. Common borosilicate rod could be bought for less than $1.50/kg even in low volumes. However, if you want to buy specialty molding materials such as COP plastic and the high-index moldable glass you will have to pay more since they are quite expensive. This is just an overview, but one important thing to take note of that the basic difference in cost between molded glass and molded plastic optics lies in the processing and not in the raw materials.

Material Processing

The first processing stage includes preparing the raw materials for molding. Thermoplastic resins for plastic optical injection molding can be of extruded and cut pellet form. Precision Glass Molding requires a precision preform before molding. Preforms can be manufactured either by pile creating or by using precision ball preforms, which is an additional step that can add cost to the entire PGM process. However, if you talk of efficient material usage then glass molding is a better choice over plastic molding. It is because the excess materials from plastic molding cannot be reused in a majority of optical applications. Excess material can total to up to 98% of the total material used for plastic molding!

Pressing glass from a pile can prove to be 100% effective since plastic optics can be molded at a faster pace compared to plastic. So, you can easily overlook the material cost when compared with the processing speed of glass.

The main advantage of plastic is that the plastic injection molding has become a $141 billion industry and it is predicted to reach $277.78 billion by 2020. Due to the vast global industry size, there has been significant development and innovation in the injection molding machines and processes. Plastic optics represents only a small portion of the overall market and is dependent entirely on the unique requirements of molded optics. In contrast PGM is industry specific and relatively young.

Precision glass molding can be defined as a high-temperature compression molding process conducted in a well-organized environment with the use of optical-quality molds. It results in the manufacturing of optical-quality lenses that employs mostly exclusive equipment.

In recent years, however, the world has seen significant improvements in the PGM process. While the cycle time for an injection-molded 6-mm diameter plastic lens can be less than 30 seconds, an equivalent glass molded lens may take up to 15 minutes. You can minimize the time difference by using increased cavitation and transfer molding. However, since glass molding requires longer processing time and higher temperature, it reduced the lifetime of a tool. The process also increases the relative cost of components. In such a case, many opt for plastic optics since it is ideal for very high-volume applications.

The basic advantages of plastic optics over traditional ground and polished glass lenses are low weight, low cost, ability to generate aspheric surfaces, and adding integral features quite easily and quickly. However, when you compare molded plastic optics with PGM, many of these benefits seem to disappear. Precision glass molding has high capability of manufacturing aspheric or micro-optic components. We now see the increased use of PGM lenses in the highest-volume, lowest-cost applications such as assembling of cell phone lens.

Hire Dedicated Lens Design Consultant in NH to Get Custom Lenses Offering Maximum Performance

Importance of Lenses

Lenses are one of the most crucial devices in the field of optics and optical design. Lenses are used in commercial, industrial, medical, military and such other sectors. Lenses make the invisible visible to naked eyes. For example, in medical laboratories, microscopes are used to identify bacteria and such other microbes; in movie theaters, the projectors throw light on the screen for starting a movie, and so on. Lenses are transparent thin glass or plastic with at least one curved surface. When light falls on a lens, the light rays get refracted to make an object either look smaller or bigger than its normal size.

Types of Lenses

Lenses can be convex, concave or compound. The most common types of lenses widely used across industries worldwide are convex lens. It has one flat side and one bulging side. The central part is thicker than the sides. They are also called positive lenses. There are basically three types of positive lenses -

Double Convex lens

Plano Convex lens and,

Positive Meniscus lens

Negative lenses are those ones that have a thinner center and thick edges. Unlike positive lenses, negative lenses do not produce real images. They are also of three types:

Double Concave lens

Plano Concave lens and,

Negative Meniscus lens

The various other types of lenses are used by different companies with unique business needs. Custom lenses are required by different industries to performing different types of work. A good lens design consultant in New Hampshire should be hired to get the perfect lenses you are looking for.

Things to Keep in Mind When Designing Lens

At the time of lens designing, certain factors need to be taken into consideration. For example, the performance of a lens whether used in a camera or microscope varies with the wavelength range. For collimating and focusing lenses, the wavelength range is usually 635nm to 980nm while the design wavelength can be 780nm.

It is only a good engineer who can clearly identify the ‘sweet spot’ of a lens. It is that spot or the aperture setting where maximum performance of the lens is attainable. Many of us don’t know one simple fact that it is not possible for lens say of a camera to retain maximum aperture setting for the same level of sharpness all the time.

It is only an experienced lens designer who can correctly use the materials to manufacture volumes of lenses within a short span of time. Even though same size and thickness of lenses are manufactured, when working with them, people may note variations with regard to the performance of a lens when rays of light fall on it. The outcome might be because of dispersion of the lens glass. It results in the change of refraction index with lens wavelength.

Experienced team of lens designers can easily meet the varied lens designing needs of a large number of clients throughout the year. Some of the most popular types of lenses designed are as follows:

Zoom Lenses

High resolution, compressed zoom lenses are manufactured by dedicated optical engineers using latest technology and equipment. Such kind of lenses is used to closely track objects by zooming in the focused object. Zoom lenses are mainly used in CCTV.

UV, SWIR, LWIR Lenses

Ultraviolet and Infrared lenses are required by many companies; however manufacturing such lenses are quite costly. Short-wave and long-wave infrared lenses are designed to meet specific requirements of individuals. For example, LWIR lenses help a person easily see through dust or smoke. The field of view of a SWIR and LWIR lens depends primarily on the focal length and the size of the detector.

Non-browning Lenses

Best of lens design consultant in NH is specialized in developing a complete range of non-browning or radiation resistant lenses for radioactive environments. These lenses are produced using high quality glass or plastic and they offer maximum performance in such delicate settings.

Lens Adapters

Often individuals require lens adapters. These are nothing but additional lenses that are utilized to change the viewing field or image format. Experienced lens designers will design and develop lens adapters to help the client get hi-resolution images with negligible alteration.

Qualities of a Good Lens Design Consultant

A good lens engineer will always work toward manufacturing lenses that are just right for the customer. He or she must have a solid understanding of the physics of light, the behavior of various imaging items, and how lenses work in different objects. It is better to contact a lens designer who has knowledge and practical experience in working with opto-mechanical design and electronics design. Having a past working experience with various optical design projects will help the engineer come up with a great lens design.

For designing an ideal lens, the engineer needs to be tolerant during the manufacturing process. Tight tolerances help to get the same kind of lenses for use in multiple systems. It helps to produce better image quality with minimal distortion.

Best of Optical Design Consultants have Complete Knowledge to Offer Custom, High Quality LEDs

With the rise of global warming and carbon footprint on our planet, a rising number of private and public organizations are becoming more conscious to use energy saving lighting system than the traditional halogen lights that consume more power. LED lights bring greater energy efficiency and help to save a considerable amount of running costs of various companies. Today, LED is used to design and develop flash lights, street lights, microscopes, and lights used in aviation, automobile and such other commercial sectors. Moreover, LED lights are also used at home, in light pipes, and more.

Customers looking for high quality optics, reflectors and lenses for use in LED (Light-Emitting Diode) applications should get in touch with an experienced optical design consultant to get the desired end-product on time. There are many companies that have highly skilled optical designers working day and night to come up with a unique design that would highly please the customers. LED has the potentiality of offering dozens of new applications; however for that purpose, an optical designer needs to be well educated about the infrastructure and use of new components. The most important things such as achieving constant light patterns, mixing of various colors and getting the specified beam patterns from a point source such as LED require the active participation of an experienced optical engineer.

One of the main qualities of a good optical design consultant is to have in-depth knowledge about engineering, physics with great problem solving skills. These professionals should have extensive information about how light falls on an object and gets reflected, about color mixing, and more. For example, they must have full knowledge about the fact that when light falls on a glass sheet, light gets reflected as well as transmitted whereas when light falls on a mirror, it gets totally reflected. There are two aspects of light – the visible one and the invisible one. The visible part we get to see while the invisible - infrared and ultraviolet rays of the sun we cannot see. Best of optical engineers are aware of these properties and use the same to create a wide variety of lighting products.

With changing time, companies are demanding more advanced and new types of LED lighting solutions. Thus, the optical designers need to sharpen their skills to provide customized solutions as wanted by the customers from time to time. However, there are no set optical parameters for designing and developing LEDs.

Normally, experienced optical design consultants offer LED lighting solutions based on Efficiency, Materials, Beam Patterns, etc.

Efficiency

Optical efficiency means the amount of light that is coming out from a defined optical surface. Efficiency is taken into account to find out how worthy an optical system is to successfully handle light sent into it. For example, a good quality lens will have up to 91% of efficiency.

A good optical designer will always set the light output of the system. The designer will access LED datasheet to go through the specifications for luminous flux and use the mentioned parameters to choose the number of LEDs required for the system. An efficient designer will also work upon the LED array configuration to get a preferred driver topology – single or multiple drivers.

For one or multiple LEDs, an optical engineer set a ray set. It is a map of 10,000 to 1, 0000,000 individual rays of light as they get emitted from LED. This ray set is used to enter the data into a ray tracing program such as Zemax. A company with a good track record usually has a ray set for major LED (CREE, Osram, Luminus, Luxeon, etc.). In case, you are willing to work with a less popular brand, your hired company may request you to provide the LED ray set for delivering the final lighting solution to meet your needs.
