Quartz glass for optics is a silica single component specialty industrial technical glass. The hardness of this kind of glass can reach Mohs 7, high temperature resistance, low expansion coefficient, thermal shock resistance, chemical stability and good electrical insulation performance, and can transmit ultraviolet and infrared rays. In addition to hydrofluoric acid and hot phosphoric acid, it has good acid resistance to general acids. According to transparency, it is divided into two categories: transparent and opaque. According to the purity, it is divided into three categories: high-purity, ordinary and doped.

1. Incredible thermal shock resistance (can be taken out of red heat and thrown into water without breaking)
2. Low thermal expansion coefficient
3. Light transmission properties from UV to IR
4. Good chemical resistance
5. Excellent electrical insulator
Quartz glass for optics generally has good light transmission, high temperature resistance, corrosion resistance, electrical insulation, etc., so it is also widely used in high-tech product industries that require high temperature, corrosion resistance, light transmission, filtering and other production process environments.
