JGS high-purity optical quartz sheet

JGS high-purity optical quartz sheet is a top-level optical material made from silicon dioxide (SiO ₂) with a purity of over 99.99% as the substrate, which is melted at high temperature and precision processed. It has excellent broad-spectrum transmittance, extremely low coefficient of thermal expansion, and outstanding high temperature and corrosion resistance. As the core component of high-end optical systems, this product is perfectly adapted to various harsh environments ranging from deep ultraviolet to near-infrared, and is the preferred substrate for semiconductor, laser, optical communication, and precision instrument fields.

FAQ

Q: What are the main differences between JGS1, JGS2, and JGS3 quartz sheets?

A: These three grades are mainly targeted at different spectral band requirements. JGS1 (far ultraviolet optical quartz glass) has excellent transmittance in the 185nm-2500nm wavelength range, making it particularly suitable for the short wave ultraviolet region; JGS2 (UV optical quartz glass) is suitable for the 220nm-2500nm wavelength range and contains trace metal impurities, with high cost-effectiveness; JGS3 (infrared optical quartz glass) contains almost no hydroxyl groups and is designed specifically for the infrared band of 260nm-3500nm, with excellent infrared transmission performance.

Q: What specifications of customized services can you provide?

A: We support comprehensive size and process customization. The standard dimensions range from 20 × 20mm to 200 × 200mm, and the thickness can be flexibly adjusted between 0.1mm and 25mm. In addition to standard circular and square shapes, we can also perform CNC precision machining such as irregular cutting, punching, slotting, and provide surface treatment services such as single-sided or double-sided polishing, coating (anti reflective film, reflective film, etc.).

Q: What are the temperature resistance and chemical stability of JGS high-purity optical quartz sheets?

A: The softening temperature of this product is as high as 1730 ℃, and the long-term use temperature can reach 1100 ℃ -1200 ℃, and it can withstand severe thermal shock without bursting. In terms of chemical stability, except for hydrofluoric acid, it has strong corrosion resistance to the vast majority of acidic and alkaline chemicals, making it very suitable for long-term stable operation under harsh conditions of high temperature and strong corrosion.

Customer application case sharing

A well-known university physics laboratory faced a huge problem of signal attenuation caused by severe absorption of ordinary optical glass in the short wavelength ultraviolet region during a deep ultraviolet fluorescence microscopy imaging study. They urgently need a window material that can efficiently transmit light in the 185nm-250nm wavelength range and withstand high-intensity excitation light.

After a thorough understanding of the requirements, we recommended and customized a batch of high-precision JGS1 optical quartz sheets for it. Through precise double-sided polishing technology, we control the surface quality at the 10-5 scratch dig level, greatly reducing light scattering losses. After being put into use, customers reported that the quartz window not only significantly improved the transmission efficiency of ultraviolet light, making the capture of weak fluorescence signals clearer, but also, under long-term high-energy laser irradiation, the material did not show any aging or damage, perfectly ensuring the continuity and accuracy of experimental data.
