涂有AR膜与AG膜后对玻璃透光率的影响

Analysis of Transmittance of Glass Coated with AR Film and AG Film

对光线的反射率、吸收率和透过率是玻璃的三个重要参数。AR膜和AG膜的共同点是通过减少玻璃反射光增加透光,实现该功能的同时并实现其特定功能。浮法玻璃、超白玻璃在镀有AR膜后或涂有AG膜后,透光率分别会有增加;涂有AR膜和AG膜二种膜后,玻璃透光率的变化不一定是叠加的。归纳二种玻璃与二种增透膜单独和结合的10种类别,分别对其光学性质进行研究,扩大超白玻璃与增透膜的组合应用,在理论和实践上都有重要意义。

The reflectivity,absorptivity and transmissivity of light are three important parameters of glass.The common point of AR film and AG film is to increase light transmission by reducing the reflected light of glass,to achieve this function and realize its specific function at the same time.In terms of the light transmittance of glass,the light transmittance of float glass and ultra white glass will increase after AR film or AG film is coated,respectively;after AR film and AG film are coated,the change of the light transmittance of glass does not necessarily overlap.It is of great significance in theory and practice to sum up ten categories of two kinds of glass and two kinds of antireflection films,to study their optical properties and to expand the combined application of ultra white glass and antireflection films.
