Optical quartz glass
With silica as the main component, it has high temperature resistance, low expansion coefficient, high mechanical strength, good chemical properties, etc. The characteristics of optical quartz glass are used to manufacture prisms, lenses, windows and reflections with special requirements for various wavelengths. Mirror and so on. In addition, there are photomasks for large-scale integrated circuit manufacturing, liquid crystal display panels, and image-based disc-based thin-plate glass; magneto-optical glass that rotates when the light passes through the glass in the direction of magnetic lines of force; light is transmitted in a certain direction. In the case of ultrasonic glass, acousto-optic glass in which light is diffracted, reflected, concentrated, or optically shifted occurs.
