In the optical component, the domestic optical quartz glass can be mainly divided into three grades: JGS1, JGS2, and JGS3 according to the spectral application range:
1. JGS1 (Far Ultraviolet Optical Quartz Glass/ Synthetic Fused Silica)
It is an optical quartz glass melted with high purity hydrogenand oxygen. Excellent UV transmission performance, especially in the short-wave UV range, its transmission performance far exceeds that of all other glasses, with a transmittance of 90% at 185nm, which is an excellent optical material in the range of 185-2500nm.
2. JGS2 (Ultraviolet Optical Quartz Glass/ Fused Quartz)
It is an optical quartz glass melted with hydrogenand oxygen. It is a good material in the range of 220-2500nm.
3. JGS3 (Infrared Optical Quartz Glass)
It has high infrared transmission performance, the transmission rate can reach more than 85%. It is an optical material with a wavelength range of 260-3500nm.
Besides domestic materials, we also offer materials in all grades and specifications from major manufacturers such as Corning, SCHOTT and Heraeus. The material has high purity and uniformity, and the finished product has better and more stable performance. Depending on the customer's custom needs, considering the optical, mechanical and chemical properties of the material, we recommend more suitable materials or other specified materialsfor processing.

Quartz glass is a chemically stable material that does not react with water, salt solutions and most acids, only hydrofluoric acid can corrode quartz glass. Quartz glass is very sensitive to all alkali and alkaline earth compounds, the extremely slight traces of these compounds willcause the crystallization of quartz glass at high temperatures.
