| 摘 要： | 为了修正紫外偏光镜透射光束偏离角,提出了一种新的设计思路,通过改变冰洲石一端的结构角来实现透射光束无偏离.以0nm波长为例,给出了修正角与结构角的关系式;还研究了透射光束的偏离角与波长的关系,并通过数值计算软件进行了分析.结果表明,在240nm～410nm的波段内,改进形式的紫外偏光镜透射光束偏离角小于0.04°.

| Abstract: | In order to modify the deviation angle of ultraviolet polarizing prism of iceland crystal and barium fluoride,a new design was given by changing the structure angle of the iceland crystal. The relation between modified angle and structure angle was given at 303nm,and the relation of the deviation angle with wavelength was also investigated. The results obtained by the mathematical software ORIGIN7.0 indicated that the deviation angle was less than 0.04°in the range of 240nm～410nm. |
