I plant the production of optical quartz glass window film, can resist high temperature and high pressure, which is mainly used in special light source, optical instruments, optoelectronics, military industry, metallurgy industry, semiconductor, optical communication field. It can test temperature: 1200 degrees, softening temperature: 1730 degrees, the specific parameters are as follows.
1.JGS1 (far ultraviolet optical quartz glass)
It is made of optical quartz glass melting high purity oxygen. With excellent penetration performance of UV, especially in short wave ultraviolet range, the transmittance is far more than all the other glass, in 185m Mu at the transmission rate of up to 90%, 185 - 2500m Mu band range of excellent optical materials.
2.JGS2 (ultraviolet optical quartz glass)
It is made of optical quartz glass melting oxygen. It is a good material in the range of 220 - 2500m.
3.JGS3: (infrared quartz glass)
It is a high penetration infrared performance, the transmission rate of up to 85% or more, its application band range of 260 - 3500m.
