Polarization beam splitting prism (PBS) is mainly used to separate S polarization and P polarization, split the non-polarized incident light into two vertical linearly polarized lights, and the light absorption is negligible. Widely used, high extinction ratio. CR-EW Optic provides a variety of polarization optical prisms such as PBS, which are used in spectrophotometers, interferometers, tunable lasers, etc.
