消光

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

激光偏光棱镜数较多，透射比、消光比、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.

磁光调锁相椭偏仪采用交流法拉第磁光调及相敏检波来检测消光点,具有抗干扰能力强,角分辨能力高等优点。
