Polarization Beamsplitter Cubes
Polarizing Cube Beamsplitters split randomly polarized beams into two orthogonal, linearly, polarized compoents. S-polarized light is reflected at a 90 degree angle while P-polarized light is transmitted. Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of prims.
