消光

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

激偏棱镜技术参数较多，透射比、消比、视场、分束、长度孔径比。

The magnetooptic self-nulled ellipsometer,with ac Farady magnetooptic modulating and phase locking to detect nulled point,has the high abilities of prevent interference and angular recognize.

调锁相椭偏仪采用交流法拉第调及相敏检波来检测消点,具有抗干扰能,分辨能高优点。
