Quartz ring has its unique optical properties, is the best material which through the ultraviolet. It can be either through far ultraviolet, visible and near infrared spectra. Customers can choose which they desired from 185 to 3500 nm wavelength range.
As quartz ring have characteristics of high temperature resistant, minimal coefficient of thermal expansion, good chemical stability. Its air bubble, streak, homogeneity and double refraction can compare with ordinary optical ring. To sum up, it is the essential optical materials that can work under various bad occasions with high stability optical coefficient. |
