摘　　要：利用惠更斯作图法,给出了一种计算平行分束偏光镜中e光离散角的新方法,得出了最大离散角时的分束镜设计,并对不同材料的Walk off型偏振无关光隔离器用平行分束偏光镜的性能作了分析与比较,得出了最佳的材料选择。By using Huygens,s graphing method, a new method calculating walkoff angle of extraordinary is presented in parallel splitting polarizer, and the design of the polarizer was obtained when the walkoff angle is maximal. Taking an analysis and comparison to different polarizers for walkoff mode polarizationindependent isolators, it gives the best selection of the crystal.
