| 摘 要： | 给出了基于双Wollaston棱镜的对称分束角偏光分束镜的一种新的设计思想,即通过改变组成棱镜的三部分之一的晶体光轴的方向来实现出射光束的对称分束,并研究了晶体光轴的旋转角与棱镜的结构角以及光波长的关系。结果表明,这种设计不但能实现光束的对称分束,而且还具有良好的偏光性能。

| Abstract: | A new designing of symmetric polarization beamsplitting prism is given, the prism realizes symmetric beamsplitting through changing the crystal axis' direction of one of the three components. The relations between crystal axis' angle and prism's structural angle and wavelenth are also researched. The result shows that this kind of prism not only can realize the beam's symmetric splitting, but has good polarization performance. |
