Splitting angle and light intensity splitting ratio of single-element polarized beam splitting prisms

In order to study the splitting angle and light intensity splitting ratio changing with the structure of a single-element polarized beam splitting prism,at first how the o light and e light changing with the orientation of principal axis,the structure angle of the prism and the incident angle was analyzed theoretically.Then how the splitting angle and light intensity splitting ratio changing with different incident angles was measured experimentally.The mathematical expression of the splitting angle and light intensity splitting ratio changing with the orientation of principal axis,the structure angle of prism and the incident angle was deduced,and the experimental data of the splitting angle and light intensity splitting ratio changing with the incident angle were obtained.The results indicate: The tested result is well concordant with the theoretical calculation,and the splitting angle is about 1/2 of the incident angle.
