Optical glass has excellent spectral properties
2021-10-15 11:05:42

Glass that can change the propagation direction of light and the relative spectral distribution of ultraviolet, visible or infrared light is called optical glass. Optical glass is a kind of special glass containing only a single component of silica. The outstanding advantage of optical glass is that it has unique comprehensive properties that other materials do not have, that is, very low thermal conductivity, excellent thermal vibration resistance, very high deformation temperature and softening temperature, very low thermal conductivity, very low dielectric loss and optical transmission ability in a wide spectral range from ultraviolet to infrared.

The advantages of optical glass are as follows:

It has extremely low coefficient of thermal expansion, extremely high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best UV spectral performance, visible light and near-infrared spectral performance, and has higher mechanical properties than ordinary glass.

Optical glass has excellent spectral properties. It transmits both infrared and ultraviolet light. Optical glass has good visible light transmission performance. For some optical systems that require both visible light and infrared light, this kind of glass is an ideal material. In the application of infrared technology, infrared direction finder, infrared camera, infrared commutator and infrared communication equipment equipped with infrared optical glass lens, mirror and other optical elements have important applications in various fields of national economy and military.

Optical glass is an excellent industrial material in modern industrial technology, semiconductor, metallurgy, chemical industry, electric light source, communication, light industry, building materials and other industries. It is often used to make semiconductors, electro-optic sources, semi conducting communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment and high-temperature and corrosion-resistant chemical instruments. It is widely used in chemical industry, electronics, metallurgy It is widely used in building materials, national defense and other industries.
