剪切差对入射角不敏感的平行分束偏光镜的设计

Design of parallel beam splitter whose shear difference is insensitive to incident angle

就入射面为主截面的情况,分析了入射角对平行分束偏光镜剪切差的影响规律,从而得出一种当入射角在一定范围内变化时,剪切差对入射角不敏感的平行分束偏光镜的设计方法,并且这种设计是消色差的。

Analysis of the effects of incident angle on shear difference was given when incident face is just principal section. On this basis, a design of parallel beam splitter whose shear difference is insensitive to incident angle which change within a given range was also given. And it＇s find that the design is achromatic.
