Quartz glass is an excellent optical material, which has many unique advantages and can not be replaced by other optical materials.
Quartz glass has good UV transmission performance; The absorption of visible light and near-infrared light is very low, so it is the basic material for the production of optical fiber. The coefficient of thermal expansion is very small, the chemical stability is good, and the bubbles, stripes, uniformity and birefringence are comparable to those of ordinary optical glass. It is the preferred optical material for working in bad situations.
