JGS1 Quartz glass is an optical quartz glass melted with high-purity hydrogen and oxygen, which contains a large amount of hydroxyl groups (2000ppm) and has excellent UV transmittance, especially in the shortwave ultraviolet region. Its transmittance far surpasses all other glasses, the transmittance at 185um can reach 90%, and the synthesized quartz glass has a strong absorption peak at 2730nm without any particle structure. It's excellent optical materials within the wavelength range185-2500um.
