Paper Abstract

Several kinds of high reflection thin films are prepared by electron beam gun with different designs and coating materials. The reflectivity, transmission, absorption and scattering of these thin films are measured and calculated, the loss of absorption and scattering of the thin films are mainly discussed. Furthermore, the absorption of films are also analyzed under different annealing temperature, it is found that the absorption loss can be dramatically reduced after annealing. At the same time, the compositions of thin films are tested by AES (Auger electron spectroscopy) to detect whether there is impurity or contamination.
