摘　　要：　概述薄膜偏振分光镜的研究现状及其主要特点,重点分析薄膜偏振分光镜的设计原理,并利用等效折射率的方法计算中心波长的反射率。The existing circumstances and main character of thinfilm polarizing beam splitter are presented and demonstrated. The basic design principle is emphatically analyzed. At the same time, the index of reflection of central wavelength is counted by using equivalent index concept.
