Quartz glass is a special industrial technology glass composed of a single component of silica. It has a series of special physical and chemical properties and is praised as the “king of glass” by experts in the field of new materials. It is an important basic material for modern information industry, optics, photovoltaic, semiconductor and other national strategic emerging industries and national defense fields such as aerospace. Quartz glass structure characteristics of pure quartz glass consists of a single silica (SiO2) composition, Si-O silica in quartz glass short range order, long range disorder arrangement, due to the Si-O bond is strong and relatively stable, so quartz glass has high softening temperature, excellent spectral transmittance, very low thermal expansion coefficient and conductivity, high chemical stability, irradiation resistance and long working life under extreme conditions. Quartz glass has a range of excellent optical properties. Compared with ordinary glass, high purity quartz glass has good transmittance from the far ultraviolet (160nm) to the far infrared (5 μ m) extremely wide spectrum, which is not available in general optical glass. The excellent spectral transmittance and optical uniformity make quartz glass widely used in many optical devices.
Quartz glass materials are widely used in the micro lens industry due to their excellent transmission ratio in the ultraviolet to infrared continuous wavelength range. Common digital cameras, computer display screens, CCD camera lenses, medical devices and so on are used in miniature lenses.
