Abstract

Nearly all light sources are partially polarization, the photomultiplier tube, photocell detector and grating have polarization sensitive effect. When we use natural light to do some experiment, the light from the light source must be depolarized. In order to reduce the polarization sensitive effect of the detector, we need fix a depolarizer in front of the detector. Since the times of 1928, there has been considerable attention paid to the study of polychromatic light depolarizer. But there are very limited number of ways to depolarize monochromatic light. We have ever introduced some kind of single element structure monochromatic light depolarizer made by using birefringent crystal. In this article we introduce some kind of double elements structure monochromatic light depolarizer made by using some birefringent crystal and fused silica crystal. We introduce their structure character, working principle and use specification in detail.
