Open publisher page 0 citations

Abstract

Al and the protection film on different substrate materials were prepared by industrial vacuum evaporation machine.The effect of substrate materials surface roughness on the optical properties of the Al films were detail studied.The results shown that the reflectivity of Al films were much different on different substrate materials,the reflectivity and optical uniform of Al films on ABS engineering plastic is perfect.The research results will help to fabricate low cost and large scale Al reflector.
