剪切差对入射点连续可调的平行分束偏光镜

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.

Parallel beam-splitting polarization prism with shear difference changing with incident point

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.
