Optical beam splitter GCC-4110

platefor laser applications

The beamsplitter plate is a thin optical glass plate. The firs face is coated with an all-dielectric thin film having partial reflection properties.The second surface is multilayer AR coated for 45or some other specified incident angle. This beamsplitter has low absorption and high damage threshold, suitable for high energy laser applications where cemented cubes may fail. CDHC provides three kinds of plates, all with strictly guaranteed splitting ratio but are distinguished by the polarization of the incoming and outgoing beams. For BS plates, we obtain partially polarized outgoing beams for randomly polarized incoming light. For PBS plates, we obtain both s-polarized and p-polarized beams from randomly polarized incoming light. For NPBS plates, the polarization of the outgoing beams remains the same when incoming beam is 45linearly polarized or circularly polarized.
