微角分束偏光棱镜分束角的特性研究
Characteristics of splitting angles of micro-angle beam splitting polarization prisms
摘要
Abstract
In order to study splitting characteristics of micro-angle beam splitting polarization prisms,according to optical properties of calcite crystals,from propagation direction of the light in incident interface,exit interface,and prism internal,the relationship between splitting angle and wavelength was analyzed at normal incidence.For a certain wavelength,the influence of incident angle on beam splitting angle was analyzed.After the experiment of three prism samples,the results show that splitting angle of a micro-angle beam splitting polarization prism changes with the change of wavelength of the incident light.The shorter the wavelength,the greater the splitting angle.In the principal cross section of prism,the change range of incident angle is of-20°～20° and splitting angle increases nonlinearly.The results have certain value for the design and usage of micro-angle beam splitting polarization prisms.关键词
