High Power Polarization Beamsplitter Cube is optically contacted by a pair of high precision right angle prisms, the hypotenuse of one prism is coated with polarization dielectric coating, and outsides are coated with AR coating. It split randomly polarized beams into two orthogonal, linearly, polarized components. S-Polarized light is reflected at a 90 degreeangle while P-polarized light is transmitted. As there is no epoxy in optical path, it is able to withstand high power with make it suit for high density applications.
