Abstract
In order to analyze the relationships of the light intensity splitting ratio with the incident angle,the prism's structural angle and the incidence wavelength's variation with the light beam coming from natural light's oblique incidence to Glan polarizing splitting prism,the mathematical formula of the light beam are deduced according to the geometric relationship,Fresnel formula and phase matching conditions.Through the analysis,a conclusion is drawn that the light beam assumes the nonlinear relationship with the incidence angle,the prism's structural angle and the incidence wavelength's variation,which provides useful information for the development of Glan polarizing splitting prism as optical devices.
