The characteristic calculation method and interference of thin film are in charter there , we analyze the history and existing state of polarizing beam splitting prism . we deduce the basic macneille pbs equation , which are the refractive index match term and phase match term . at the same time , we calculate the refraction ratio of p polarizing light and s polariz 在第三章中,介绍了薄膜偏光分束镜的发展历史和研究现状,以及macneille薄膜偏光分束镜的设计原理,即该设计应该满足的折射率匹配条件和相位匹配条件;计算了中, c波长处p光和s光的反射率。
