Low infrared absorption JGS1 quartz glass

JGS1 quartz glass with low infrared absorption is an optical quartz material synthesized by high-purity hydrogen oxygen flame melting method. Due to its extremely high hydroxyl content (about 2000ppm), it has excellent far ultraviolet transmission performance, especially in the 185nm short wave ultraviolet region, the transmittance can reach over 90%. As a far ultraviolet optical quartz glass, it has no absorption band in the 185-2500nm wavelength range, and has extremely low thermal expansion coefficient, excellent chemical stability, and high temperature resistance (up to 1100 ℃ for long-term use). It is an indispensable basic material in photolithography technology, deep ultraviolet analysis, and precision optical systems.

Why choose low infrared absorption JGS1 quartz glass?

Q: In which application scenarios can JGS1 quartz glass mainly solve my pain points?

A: If you are facing problems such as low transmittance of deep ultraviolet light leading to poor sterilization or lithography efficiency, easy damage of ordinary window plates in high temperature or corrosive environments, or signal noise caused by poor material uniformity in optical systems, our JGS1 quartz glass can provide a perfect solution. It is particularly suitable for deep ultraviolet lithography below 185nm, UVC-LED packaging lenses, colorimetric dishes for spectral analysis instruments, and scenes with strict requirements for high-energy laser windows.

Q: What are the core advantages of this JGS1 compared to JGS2 or JGS3?

A: The core advantage lies in its ultimate ultraviolet transmission performance and material uniformity. JGS1 has no particle structure and is highly transparent in the ultraviolet and visible light regions, completely solving the problem of energy attenuation caused by absorption of ordinary quartz or JGS2 in the short wave ultraviolet region (185-250nm). Meanwhile, it does not contain the small bubbles and stripes that may exist in JGS3, providing you with a purer optical path.

Core advantages of the product:

Excellent spectral transmittance

Our JGS1 quartz glass exhibits excellent performance in the wide spectral range of 185nm to 2500nm, especially in the short wave ultraviolet region, with a much higher transmittance than similar products. At 185nm, the transmittance reaches over 90%, ensuring maximum transmission of deep ultraviolet light energy.

Ultimate physical and chemical stability

-High temperature resistance: The softening point temperature is about 1730 ℃, which can be used for a long time at 1100 ℃, and the short-term use temperature can reach 1450 ℃, suitable for extreme working conditions.

-Thermal stability: The coefficient of thermal expansion is extremely small, and it can withstand drastic temperature changes (such as heating to 1100 ℃ and not exploding when immersed in normal temperature water).

-Corrosion resistance: Except for hydrofluoric acid, it hardly reacts with other acidic substances, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel.

Customer Application Cases

Case 1: Window selection for deep ultraviolet sterilization module

-Customer requirement: A European UVC-LED module manufacturer is looking for high transmittance window materials for deep ultraviolet LED packaging below 265nm. The customer initially attempted to use regular quartz, but the measured sterilization efficiency was far below the design value.

-Our solution: After analysis, it was found that ordinary quartz has absorption in the short wave ultraviolet region. We recommended customized 0.5mm ultra-thin JGS1 quartz window panels to our customers. Utilizing the characteristic of JGS1 with no absorption band between 185-2500nm and the ultra-thin design to reduce optical loss.

-Final effect: After replacing the material, the actual optical power density of the customer module in the 265nm band increased by more than 30%, and the overall sterilization rate met the standard. The product successfully entered the medical grade market.

Case 2: Customization of high-precision spectral analysis colorimetric dishes

-Customer Requirement: A US biotechnology company requires a quartz colorimetric dish for protein analysis below 200nm wavelength, with no fluorescence interference and minimal pairing error.

-Our solution: Using our JGS1 far ultraviolet quartz glass, we have customized a high-precision que colorimetric dish with an optical path length of 5mm and four sided transparency through precision annealing and optical cold processing technology. JGS1 has a strong absorption peak at 2600-2800nm, but there is no absorption band at the 200nm band required by the customer, and it is non emissive and stable in light radiation.

-Final effect: Customer feedback: Our colorimetric dish has excellent data repeatability in the deep ultraviolet band, completely replacing its original high priced imported supplier and shortening the delivery cycle by 50%.

Case 3: High temperature resistant windows in semiconductor equipment

-Customer demand: A domestic semiconductor equipment manufacturer requires an observation window that can withstand high temperatures of 1100 ℃ and maintain high flatness even at large sizes (such as 200mm diameter).

-Our solution: By utilizing the low thermal expansion coefficient of JGS1 material, we have customized large-sized quartz windows with a thickness of up to 10mm. We strictly control the elimination of thermal stress during the processing to ensure that the product does not deform or explode in high-temperature chambers.

-Final effect: The window performs stably in CVD equipment, with a long-term unchanged transmittance, and has been recognized by terminal chip manufacturers.

Whether in deep ultraviolet lithography, semiconductor manufacturing, medical analysis, or military research, low infrared absorption JGS1 quartz glass has become your most reliable optical companion with its ultimate UV transparent appearance and stability.
