The polarized prism is made of a pair of high precision right angle prisms. One of the prisms on the slope of the multi-layer dielectric spectroscopy. When a group of unpolarized light perpendicular to the incident surface, divided into two polarized light, from two mutually perpendicular to the adjacent surface, the polarization state perpendicular to each other. The transmitted light is P light, and the reflected light is S light.
