The optical properties of silica quartz sight glass

The optical properties of silica quartz sight glass has its own characteristics. It can penetrate far ultraviolet spectrum, and is the best material for all ultraviolet materials. It can penetrate visible and near infrared spectrum. Users can choose any desired variety from 185-3500 to M band according to their needs.
The refractive index of quartz sight glass is very small, the refractive index of quartz sight glass is ND=1.45845, and the value of the optical quartz sight glass in 20oC is ND=1.4586 + 4 * 10-4. The refractive index in the ultraviolet part (214.4 nm -280.3 nm) is 1.5341-1.4942, in the visible part (404.6 nm -766.5 nm) 1.4698-1.45413, and in the infrared part (863 nm -36501 nm) is 1.45251-1.47454, and the refractive index decreases with wavelength.
 
Transparent quartz sight glass has excellent infrared and UV transmittance. In common quartz sight glass, there is a main absorption peak and two spectral waves at the base of 2.73 microns in the infrared spectrum. For the purpose of foundation, the company adopts vacuum pressurized or hydrogen free flame melting to produce optical quartz sight glass. The UV transmittance of quartz sight glass in impurities, especially the relationship between iron content, low content of quartz sight glass can be used as the ultraviolet quartz sight glass.
