Optical glass use

Glass materials 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 protection glass and optical quartz glass, etc. Optical glass has a high degree of transparency, a high degree of chemical and physical uniformity, and has specific and precise optical constants. Crown glass is generally used as a convex lens, and flint glass is used as a concave lens. Usually crown glass belongs to alkali-containing borosilicate system, light crown glass belongs to aluminosilicate system, heavy crown glass and barium flint glass belong to alkali-free borosilicate system, and most flint glass belongs to lead potassium silicate system. With the continuous expansion of the application field of optical glass, its variety is constantly expanding, and its composition includes almost all the elements in the periodic table. An inorganic glassy material that transmits light through refraction, reflection, or transmission, or changes the intensity or spectral distribution of light through absorption. It has stable optical properties and high optical uniformity.
