Beam splitters for Co2 laser
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 10.6µm 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.
