Flatness: 0.05mm can be done within a quartz glass manufacturing prisms, lenses and requires working with a high degree of stability in the harsh light system is essential occasions The optical material. It is widely used in space technology, detecting and tracking systems, spectral instruments, as well as a variety of high-temperature operation of the window material. Our current production of optical quartz glass varieties, the production process is not the same, in order to facilitate the user to select: 1) the far ultraviolet quartz glass (JGS1): liquid silicon tetrachloride with high-purity hydrogen flame directly melted into high-quality optical quartz glass. Such glass can be completely free of bubbles, having a satisfactory UV performance, particularly in the short-wave UV region, which surpass all the other glass permeation performance, transmittance 185mμ is up to 85% at 185 excellent optical wavelength range within -2500mμ material. Because of this glass contains OH groups, so the infrared transmission performance is poor, especially in the vicinity of 2.7μ had a large absorption rate; 2) ultraviolet quartz glass (JGS2): with an oxyhydrogen flame to melt Advanced crystal powder made of optical quartz glass. It is a good material within 220-2500mLl wavelength range; 3) infrared optical quartz glass (JGS3): Advanced crystal is melted in a vacuum furnace in the pressurized powder made of optical material. Has a high performance infrared transparent, 1-3μ transmittance up to 90%. Applications in the wavelength range 260-3500mμ; 4) through the whole optical quartz glass: high-purity raw material is used, a hydrogen-free heat source for melting glass made of quartz, applications in the wavelength range 200-3500mμ, UV 240mμ, infrared 2.7μ no absorption peak.
