PVD coating generally refers to the purpose of coating on the surface of optical parts to reduce or increase light reflection, beam splitting, color separation, light filtering, polarization, etc. The main uses of optical coating materials are divided into composite film, color film, and antireflection film , UV-transmitting film, laser device filter, protective film, transparent conductive film, color-changing film, excellent broadband anti-reflection film, magnetic film, visible light region anti-reflection film, infrared anti-reflection film, spectroscopic film, multilayer film, high Reflective film, resistance film, heat reflection film, cold light lamp, cold light bowl, various lens coatings, etc. Optical coating has a wide range of functions and various types of coating materials. Ketai New Materials provides various coating materials for various coating companies, mainly including target materials and evaporation coating materials.
