Optical Silica (SiO2) is a synthetic molten, amorphous quartz glass. They are manufactured using several different processes. Quartz glass has an extraordinary high optical transmissivity for ultraviolet light. Due to its low coefficient of thermal expansion, quartz glass can resist very high operating temperatures. The very good UV-light transparency of quartz glass in optical applications can’t be beaten by any other industrial glass material.
