摘　　要：为了既节省冰洲石晶体材料，又可以实现剪切差对入射点的连续可调，将光学玻璃（ZBaF3）与冰洲石结合，并用溴代萘胶合，设计了一种新型平行分束偏光镜。实验测试表明，棱镜出射的o光透射比高于85％，消光比优于10^-5；e光透射比高于70％，消光比优于10^-3。结果表明，该设计在节省冰洲石的前提下，不仅保持了良好性能，还实现性能创新，给使用带来便利，具有良好的应用前景。In order to save the rare iceland and adjust shear difference continuously with incidence points, a new type of parallel beam-splitting polarization prism was designed by adhering the optical glass （ZBaF3 ）and iceland with bromonaphthalene. The experiments indicate that the transmittance of o light and e light are more than 85% and 70% respectively, and their extinction ratios are better than 10^-5 and 10^-3 respectively. On the premise of saving iceland, the prism not only keeps good performance, but also brings great convenience to use by its new performance. Therefore, the design has good prospects.
