Chromium Oxide,Cr2O3 sputtering target
Development of coating
In 1817, the chemical coating the surface of the first optical components used in the preparation of protective film. Then. Fraunhof Germany with concentrated sulfuric acid or nitric acid erosion of glass, the first chance to obtain anti-reflection film, 1835 years ago was deposited by wet chemical method of selection of the silver mirror film which was first prepared in the world of optical films. Later, people make various optical films in the chemical solution and the vapor deposition. 50 years, faster than a large number of window glass antireflective film applications, the chemical solution deposition method gradually being replaced by vacuum coating.
