As optical systems continue to evolve, HHV’s TFOD ensures its solutions meet the most demanding specifications in terms of optical performance, environmental durability, and consistency.

To better understand the capabilities and standards of HHV’s TFOD, here are 10 key technical questions often used to assess specifications and ensure quality assurance.

1) What is the standard wavelength range supported by the coatings (e.g., UV, visible, NIR, IR)?

Answer: HHVAT’s optical coatings are designed to support a wide spectral range, covering applications across the ultraviolet (UV), visible, and near-infrared (NIR) regions. Specifically, the UV coatings operate effectively in the 250 nm to 400 nm range, suitable for high-energy optical systems. The visible spectrum, which spans from 400 nm to 800 nm, is addressed through coatings optimized for high transmission and minimal reflection in this range—ideal for consumer optics, displays, and imaging systems. For applications in thermal imaging, remote sensing, or communication systems, HHVAT also provides coatings that perform in the NIR region, covering wavelengths from 800 nm up to 2500 nm. These broad wavelength capabilities ensure compatibility with a wide variety of optical applications.

2) What is the achievable thickness control accuracy for single and multilayer films?

Answer: HHVAT employs precise thin-film deposition technologies that enable high accuracy in coating thickness control. For single-layer films, thickness can be controlled with an accuracy of up to 1 nanometer (nm), which is critical for achieving the required optical performance, particularly in narrowband filters or anti-reflective layers. When it comes to multilayer coatings, HHVAT has the capability to deposit up to 150 layers with tight control over each layer's thickness and uniformity. This is particularly essential for designing complex coatings such as dielectric mirrors, bandpass filters, and high-reflectivity (HR) stacks where precise layer architecture governs spectral performance.

3) What are the typical reflectance and transmittance specifications for common coatings like AR (anti-reflective), HR (high reflective), and filters?

Answer: HHVAT’s optical coatings meet stringent optical specifications for performance and reliability. For anti-reflective (AR) coatings, the typical reflectance is maintained at ≤ 0.5%, ensuring minimal light loss and glare, vital for lenses and imaging systems. In terms of transmittance, coatings are optimized to allow up to 90% of light transmission, depending on the substrate and design. For optical density (OD) laser protective glasses, HHVAT offers coatings that achieve OD values up to 7, which indicates extremely high attenuation of specific laser wavelengths, making them suitable for safety and defense-related applications where laser protection is critical.

4) What kind of coating is done in HHVAT?

Answer:

HHVAT provides both:

PVD (Physical Vapor Deposition):

E-Beam (Electron Beam Evaporation) – for high-purity coatings.

Magnetron Sputtering – gives dense and uniform coatings.

Thermal Evaporation – for simple metal or dielectric films.

CVD (Chemical Vapor Deposition):

DLC (Diamond-Like Carbon) – extremely hard and durable coating.

These techniques are selected based on material, durability, and optical performance requirements.

5) What is the maximum optical density (OD) that can be achieved for blocking filters or laser protection applications?

Answer: HHV Advanced Technologies (HHVAT) provides a full spectrum of anti-reflective coating (ARC) solutions, covering a wide range of applications and substrates. The company is equipped to handle all types of ARC requirements, from standard optical components to complex, application-specific coatings. However, HHVAT has built specialized expertise in certain critical areas, where high-performance ARC is essential:

Ophthalmic Lenses – Coatings are tailored for improved clarity, reduced glare, and enhanced visual comfort for eyewear users.

High-Transmission Optical Components – Designed for applications requiring maximum light throughput across the UV to IR range.

Germanium Substrates – Specialized ARC coatings are developed for Germanium optics, commonly used in infrared (IR) imaging systems, including night vision and thermal cameras.

These focused capabilities highlight HHVAT’s ability not only to deliver general-purpose ARC coatings but also to engineer precision coatings for advanced, high-demand applications.

6) What is the uniformity specification for film thickness across the entire substrate surface?

Answer: HHVAT ensures exceptional uniformity in film thickness, achieving greater than 99% consistency across the entire substrate surface. This high level of uniformity is critical for maintaining consistent optical performance, especially in precision optics and large-area coatings. Such accuracy reflects the advanced process control and equipment capability at HHVAT, making it well-suited for applications where even minor thickness variations can impact functionality.

7) What level of environmental durability is tested (e.g., MIL-STD-810 for humidity, abrasion, salt fog)?

Answer:Durability tests include:

Humidity & Temperature Cycling – simulates harsh environmental conditions.

Salt Fog – tests corrosion resistance.

Abrasion – checks wear resistance.

Adhesion – ensures coating bonds well to the substrate.

Wiper Test – simulates real-world surface cleaning.

8) What surface quality standards (e.g., scratch-dig 60-40) are maintained on optical components?

Answer: HHVAT maintains stringent surface quality standards to ensure high optical performance and durability. Optical components are manufactured with a surface finish of λ/10 (lambda by 10), which also reflects excellent parallelism—a critical requirement for minimizing optical aberrations and ensuring beam accuracy in high-precision systems. In addition, HHVAT achieves surface roughness levels below 3 Å (angstroms), particularly in demanding applications such as Zinc Sulphide (ZnS) domes and laser optics. This level of surface quality ensures minimal scattering and high transmission efficiency, making the optics suitable for advanced imaging, defence, and laser-based systems.

9) What in-process and post-deposition testing methods are used (e.g., spectrophotometry, ellipsometry, interferometry)?

Answer: HHVAT employs a comprehensive set of in-process and post-deposition testing methods to ensure coating precision, performance, and reliability. During the coating process, Optical Thickness Monitoring (OTM) is used for real-time, in-situ spectral monitoring, allowing for precise control of layer thickness. Post-deposition, the coatings are evaluated using spectrophotometry across various ranges—UV-Visible, NIR (Near-Infrared), and FTIR (Fourier-Transform Infrared)—to measure transmission and reflection characteristics. Additionally, stylus profilometry is performed to assess physical thickness and surface profiles, while contact angle measurements are conducted to evaluate surface energy and wettability. These combined techniques ensure that every coating meets the required optical and physical specifications for advanced applications.

10) Are customized coatings or substrate shapes and sizes supported for specialized applications?

Answer: Yes, HHVAT supports:

Custom shapes and sizes – from telescopic mirrors to eyewear lenses

Coating types – metallic, ARC, DLC, etc.
