Optical glass has a wide range of uses
Glass that can change the direction of light propagation and change the relative spectral distribution of ultraviolet, visible or infrared light is called optical glass. It is an inorganic glassy material that transmits light through refraction, reflection, and transmission, or changes the intensity or spectral distribution of light through absorption. It has stable optical properties and high optical uniformity.
Optical glass is a glass material used to manufacture lenses, prisms, mirrors, windows, etc. of optical instruments or mechanical systems. Including colorless optical glass (usually referred to as optical glass), colored optical glass, radiation resistant optical glass, radiation protection glass and optical quartz glass.
Optical glass has a high degree of transparency, a high degree of chemical and physical (structure and performance) uniformity, and has specific and precise optical constants. It can be divided into silicate, borate, phosphate, fluoride and chalcogenide series. There are many varieties, mainly classified according to their position in the refractive index (nD)-Abbe value (VD) diagram. Traditionally, all types of glass with nD>1.60, VD>50 and nD<1.60, VD>55 are designated as crown (K) glass, and the other types of glass are designated as flint (F) glass. 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. 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.
