| 摘 要： | 为了得到对称分束的偏光棱镜,采用了对常规渥拉斯顿棱镜进行改进的方法,即通过修正o光束的出射端面来实现对称分束.得到了o光束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o光束出射端面的修正角与棱镜的结构角之间的关系曲线和修正角与波长的关系曲线.结果表明,此种设计既可实现对称输出,并且具有设计简单,加工方便等特点.

| Abstract: | In order to get a symmetric beam splitting prism,the conventional Wollaston prism was modified,i.e.to modify the surface of o light and get symmetric beam splitting.The relation between the correction angle and prism's structure angle was given.Taking 632.8nm for example,the relation curve between the correction angle and prism's structure angle was obtained.Furthermore,the relation curve between the correction angle and wavelength was also obtained.The results indicate that this design can get symmetric beam splitting and it is simple and easy to process. |
