摘　　要：基于Wollaston棱镜的结构,给出了对称分束偏光棱镜的一种新的设计,即通过修正光束的出射端面来实现对称分束。给出了出射端面的修正角与棱镜的结构角之间的关系式。以632.8nm波长为例分析了出射端面的修正角与棱镜的结构角之间的关系曲线,并且分析了此修正角与波长的关系曲线。Based on the structure of Wollaston prism, a new design of symmetric beam splitting prism is given. From reforming the emergent end surface, we can get symmetric beam splitting. The relation between the correction angle and the prism＇ s structure angle is also given. At 632.8nm, we give the relation curve between the correction angle and the prism＇s structure angle. Furthermore, we also give the relation curve between the correction angle and wavelength.
