Polarization Cube Beamsplitter
Polarizing cube beamsplitters split randomly polarized beams into two otehogonal, linearly, polarized compoments, S-polarized light is reflected at a 90° while P-polarized light is transmitted. Each beamsplitter comsists of a pair of percision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of prisms.
High Powe Cube Polarization Beamsplitter
High power polarization beamsplitter can be facricated by BRD Optical. Same as the above, it use precision optical contacted technology which makes it has high laser damage threshold.
