Optical field相关介绍：

PVD coating generally refers to the purpose of coating on the surface of optical parts to reduce or increase the reflection, beam splitting, color separation, filter, polarization and other requirements of light The main uses of optical coating materials are divided into composite film, color film, antireflection film, ultraviolet film, laser device filter, protective film, transparent conductive film, color changing film, excellent broadband antireflection film, magnetic film, visible light region antireflection film, Infrared Antireflection film, spectroscopic film, multilayer film, high reflection film, resistance film, thermal reflection film, cold light lamp, cold light bowl, various lens coating, etc. Optical coating has a wide range of functions and a variety of coating materials. Ketai new materials provides various coating materials for various coating enterprises, mainly including target materials and evaporation coating materials.
