Beam splitters

The common Beams plitter is used to split or combine laser beam. However Polarization Beam Splitters are used to split or combine two perpendicular polarization laser beam . The polarization beamsplitters are designed for use at 45?angle of incidence and 10.6祄 wavelength. At this angle of incidence, there can be significant differences in the transmittance/reflectance values for s and p-polarizations.The performance of Beamsplitters is mainly dependent on the coating specifications.
