Polarizing beamsplitter cube

Product Info

Polarizing beamsplitter cubes split randomly polarized beams into two orthogonal, linearly polarized components: S-polarized light is reflected at a 90 deg 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 the prisms. A multi-layer antireflective coating has been applied to each face of the beamsplitter in order to produce maximum transmission efficiency.
