为了节省稀有昂贵的冰洲石晶体材料，尽量提高偏光棱镜的透射率，提出了一种采用冰洲石晶体与光学玻璃组合的方法，给出了以布儒斯特角入射来提高o光透射率的偏光棱镜设计。样品是一种在ZBaF₃玻璃中间夹冰洲石晶体薄片的三元结构，由高折射率液态胶合剂溴代萘胶合而成。实验测试表明，该偏光棱镜的透射率在95%以上，消光比优于10^－3，在一定情况下可以取代纯冰洲石晶体偏光棱镜。

In order to save the rare iceland and increase the transmittance of polarizing prism,a type of polarizing prism combination of iceland and glass is designed. The prism have super high transmittance of o light when the incident angle is Brewster's angle. The sample is made of ZBaF₃ glass and iceland,and the cemedin is C₁₀H₇Br. The experiment indicates that the transmittance of the prism is more than 95%,and the extinction ratio is better than 10^－13. It can be approved by the theory and experiment that the prism can replacement the prism which is only made of iceland in general.
