Slice plane window: ordinary optical glass is mainly refers to the traditionally used in all kinds of optical instruments ( Such as optical lenses) Colorless optical glass and colored optical glass for filters. At present there are more than 200 brands of ordinary optical glass, the chemical elements in the periodic table has 2? More than 3 element was introduced into the optical glass. For colorless optical glass, according to their chemical composition and characteristics of optical constants and consists of crown and flint. Corona class glass of PbO content is generally less than 3%, relatively low refractive index ( nd < 1. 6) Small (, the dispersion Md> 55) Or the relatively high refractive index ( nd> 1. 6) Small (, the dispersion Md> 50) When PbO content is more than 3 a, relatively high refractive index ( nd> 1. 6) , dispersion is larger, Md < 55) 。 And every kinds according to the characteristics of chemical composition of glass composition and refractive index nd and dispersion scope of Md, further divided into many types. Optical glass is the main material of manufacturing optical lens, optical instrument. Xiamen yi's optical quartz glass ( In the ordinary course of boron silicate glass raw materials to add a small amount of light sensitive material, such as AgCl, AgBr, add a small amount of sensitizing agent, such as CuO, glass becomes more sensitive to the light. Optical glass must be highly accurate index of refraction, abbe number and high transparency, high evenness. Optical glass is made of high purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium oxide in a particular formula mix, high temperature melting in the platinum crucible, stir well with ultrasonic, to bubble; Then after a long period of time slowly cooling, lest produce internal stress in the glass block. After cooling the glass block, must go through optical instrument measurement, test of purity, transparency, uniformity, refractive index and dispersion rate is standard. Qualified glass block after heating forging, MAO embryo into optical lens. Optical quartz glass using lithography and ion exchange process to produce low loss of nonlinear optical waveguide, preparation of small size intensive super fast full speed modulation integrated optical waveguide devices, as based on a large scale of data transmission and processing of information highway communication rapid processing of network information and improve the capacity of providing practical components. Nonlinear optical materials and devices has become a photonics microstructure and new. The density of the density of optical glass is users and manufacturers must understand one of the basic physical 貭. In addition, in calculating the molecular volume and molecular refraction of glass also need density data. Relevant tags: graphic window
