Vision Light coating technology is based on Hanson's expertise in synthesizing nano-particleswith precisely controlled size, physical, chemical, and electronicproperties. To get the optimal antireflective performance, there must be an intermediarytransparent layer, the refraction rate of which could balance the refractionrate of the air (refraction rate 1.0) and the glass (refraction rate 1.5).The single layer of highly porous silica thin film (refraction rate 1.27) is foundto be the ideal solution. It significantly improves the AR property and canprovide 5% to 8% enhancement of transmission compared with regular low-E glass.The nano-material based AR coatings can reach a maximum transmission rate up to99%. producing area:China
