Abstract
At present, it is a considerable shortage of natural calcite and it has some defects and restrictions in application. In order to alleviate the shortage of polarized prism material，the new alternative birefringence material-BBO was studied. Based on the light total reflection principle at the interface, the polarizing prisms with Lippich and Glan-Taylor style were designed. The value range of their structural angles and corresponding field angles, in particular the corresponding theoretical value in the frequency band from 230nm to 800nm were put forward. The result shows that this kind of material has good applicability and larger view angles in the ultraviolet wave band.This work lays the foundation for further research and development of new material polarized devices.
