What is optical glass

      Optical glass is a glass material used to manufacture lenses, prisms, mirrors, windows, etc. of optical instruments or mechanical systems. Including colorless optical glass, colored optical glass, radiation resistant optical glass, radiation resistant glass, and optical quartz glass. Optical glass has a high degree of transparency, chemical and physical uniformity, and has specific and accurate optical constants. It can be divided into silicate, borate, phosphate, fluoride, and chalcogenide series.

      Optical glass is the foundation and important component of the photoelectric technology industry. Especially after the 1990s, with the continuous integration of optics, electronic information science, and new material science, the application of optical glass as a basic material for optoelectronics in the three major fields of optical transmission, optical storage, and optoelectronic display has made rapid progress, becoming one of the basic conditions for the development of social informatization, especially optoelectronic information technology.
