Polarizing Beamsplitter Cubes

Polarizing Beamsplitter CubePolarizing Cube Beamsplitters split randomly polarized beams into two orthogonal, linearly polarized components. S-polarized light is reflected at a 90° angle, while P-polarized light is transmitted. Each beamsplitter consists of a pair of precision right angle prisms cemented together to minimize transmitted wavefront distortion, and to provide excellent parallelism between incoming and transmitted beams.
