增透膜反射率与膜层折射率及膜厚之间的关系

An Analysis of the Reflectivity and Anti-Reflective Film

为了消除人们对增透膜的错误认识,以光波的电磁理论为基础,从多光束干涉的理论出发,推导出反射率公式,通过讨论,给出了光学薄膜作为增透膜应满足的条件,以及单层光学薄膜反射率与膜层折射率及膜厚关系的曲线。

The result of this research indicates that many people misunderstand the film of increasing transmission. Based on the elertronic and magnetic wave theory of light and the theory of interference waves, this paper analyzes and explains the film of increasing transmission theory of a single layer of media film,deduces and discnsses the increasing transmission condition. The relation curve among reflectivity, anti - reflectivity and wavelength is finally given.
