5–10 mm JGS1 Transparent UV Quartz Plate

The 5–10 mm JGS1 Transparent UV Quartz Plate is a high-performance optical window material specifically designed for the far-ultraviolet to near-infrared spectrum. Crafted from high-purity synthetic quartz, it features exceptional spectral transmittance, an extremely low coefficient of thermal expansion, and outstanding chemical stability. Quartz plates in this thickness range offer excellent mechanical strength and flatness while ensuring high light transmittance, making them indispensable core components for precision optical systems.

FAQ Q1: What are the fundamental differences between JGS1 transparent UV quartz plates and JGS2 and JGS3? A: JGS1 is a far-ultraviolet optical quartz glass manufactured from synthetic quartz. It features extremely high transmittance and no absorption bands in the 185–2500 nm wavelength range, making it particularly suitable for short-wavelength ultraviolet applications. JGS2 is primarily used in the 220–2500 nm wavelength range, while JGS3 is geared toward infrared applications in the 260–3500 nm range. Q2: What are the optical advantages of quartz plates with a thickness of 5–10 mm? A: 5–10 mm is a commonly used thickness for precision optical windows and laser protection. This specification maintains extremely high transmittance from the ultraviolet to the near-infrared (with transmittance in the visible light region reaching over 93%) while providing excellent surface flatness (e.g., λ/10) and extremely low parallelism deviation, effectively reducing optical path difference and wavefront distortion. Q3: Can your company provide custom sizes and specialized coating services? A: Absolutely. We offer custom machining for outer diameters ranging from 1 mm to over 600 mm, with thickness tolerances controlled within ±0.05 mm. Additionally, our cleanroom facilities support precision coating services for single-sided/double-sided anti-reflective (AR) coatings, high-reflective (HR) coatings, and various protective coatings. Q4: Is this type of quartz plate stable in high-temperature or highly acidic/alkaline environments? A: It is extremely stable. JGS1 quartz plates have a softening point as high as 1730°C and can be used long-term at 1100°C. Except for hydrofluoric acid, it reacts with virtually no acidic substances; its acid resistance is 150 times that of stainless steel, making it fully capable of withstanding extreme chemical and thermal environments.

Corrosion-Resistant Quartz Sleeves for Water Treatment

Corrosion-resistant quartz sleeves for water treatment are core protective components specifically designed for underwater UV disinfection systems. Made from high-purity fused quartz, they offer exceptional resistance to acid and alkali corrosion and high light transmittance. They effectively isolate the lamp from water-borne corrosion while ensuring efficient transmission of 253.7 nm UV light, thereby guaranteeing the long-term, stable operation of water treatment systems. They are an ideal choice for the environmental protection and sanitation sectors.

Frequently Asked Questions (FAQ) Q1: Why do water treatment quartz sleeves require high corrosion resistance? A: Water treatment environments (such as sewage and industrial wastewater) often contain complex chemical substances. Quartz glass possesses excellent chemical stability; its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Except for hydrofluoric acid and hot phosphoric acid, it is inert to the vast majority of acids and alkalis, effectively addressing the corrosion challenges posed by harsh water quality. Q2: Do quartz sleeves affect the effectiveness of UV disinfection? A: No. We manufacture our sleeves from fused quartz with low hydroxyl content, achieving a light transmittance of over 90% in the UV spectrum (particularly at the 254 nm wavelength). This high transmittance ensures that UV light penetrates the sleeve without loss, achieving the desired disinfection and purification results. Q3: Can quartz sleeves be customized to specific sizes and shapes? A: Absolutely. We offer a full range of custom processing services, including cutting, end sealing, flaring, flaring, tapering, flanging, and frosting. Whether single-ended, double-ended, round-ended, or flat-ended, we can precisely customize them according to your equipment drawings.

Is There a Significant Difference in Light Transmittance Among Quartz Tubes with Different Wall Thicknesses

In optical design and industrial applications, wall thickness is a key geometric parameter that affects the light transmittance of quartz tubes. Theoretically, the absorption and reflection losses that occur when light passes through a quartz medium are directly related to the optical path length; an increase in wall thickness means a longer optical path, causing light transmittance to decrease exponentially. Taking high-purity fused quartz tubes in the visible light spectrum as an example, their transmittance typically exceeds 90%. However, when the wall thickness increases from 1 mm to 5 mm, transmittance in the deep ultraviolet spectrum may decrease significantly. This indicates that “wall thickness affects transmittance” is an objective physical law, but the extent of the impact depends on the specific spectral band and application scenario. In practical applications, our products effectively address the optical challenges posed by variations in wall thickness. Whether it’s ultra-thin walls required for deep-ultraviolet germicidal lamps to ensure high transmittance at 254 nm, or sufficient wall thickness needed for high-temperature tube furnaces to withstand thermal stress, we provide precise custom solutions that strike the optimal balance between mechanical strength and optical performance, thereby preventing reduced equipment efficiency or increased energy consumption caused by improper wall thickness selection.

As a professional manufacturer of custom quartz products, we fully understand the many challenges our customers face under complex operating conditions. We are committed to providing comprehensive customization services—ranging from standard to irregular shapes and from low-hydroxyl to ultra-high-purity quartz—to precisely address challenges such as transmittance decay, high-temperature crystallization deformation, and chemical corrosion.
