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、视场角、分束角、长度孔径比等。

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.

磁锁相椭偏仪采用交流法拉第磁及相敏检波来检测消点,具有抗干强,角分辨高等优点。
