PBS are used to split or combine laser beam. We can offer two most common types: plate and cubes. Plates are used for most laser applications due to their exhibit low absorption. Cubes are a convenient, protected form for low power applications. Polarization BeamSplitters are used to split or combine two perpendicular polarization laser beam. The performance of beamsplitters is mostly depended on the coating specifications. We can supply the coating curves of each types of beamsplitters. The types, coating, transmission and damage threshold should be considered when selecting suitable beamsplitter.
