Clicking on this button will recompute the vignetting factors for each field based upon the current lens data.

点击这个按键将根据当前镜头数据重新计算每个视场的渐。

Many parameters are required to describe their performance, which is transmission ratio, extinctivity ratio, angle of view field, splitting angle, etc.

激光偏光棱镜技术参数较多，透射比、消光比、视场角、分束角、长度孔径比等。
