Brief introduction of PBS polarizing beam splitting prism

The polarized beam splitting prism can divide the incident non-polarized light into two perpendicular linearly polarized light. P polarized light passes through completely, S polarized light reflects at an angle of 45 °, and the outgoing direction is 90 ° of P light. The polarizing beam splitting prism is composed of a pair of right-angle prisms. The inclined edge of one of the prisms is coated with a polarization-splitting dielectric film.
