| 摘 要： | 为了既节省稀有昂贵的冰洲石晶体材料,又实现偏振光的大剪切差输出,采用冰洲石晶体与光学玻璃组合的方法,给出一种新型平行分束偏光镜的设计。该棱镜为ZBaF3玻璃中间夹冰洲石晶体薄片的三元结构,并由大折射率液态胶合剂溴代萘胶合而成。理论分析和实验测试表明,该棱镜消光比优于10-3,且可以实现大的横向剪切。

| Abstract: | In order to save the rare iceland and increase the shear difference, a new type of parallel beam splitter combined of iceland and glass is designed. The prism is made of ZBaF3 glass,between which is iceland. The glue is C10H7Br with high refractive index. It can be approved by the theory and experiment that the extinction ratio of the parallel beam splitter is better than 10^-3 ,and the shear difference is improved too. |
