Cube Polarizing Beam Splitter

Cube Polarizing Beam Splitter

Polarizing Cube Beam splitter split randomly polarized beams into two orthogonal, linearly, polarized components. S-polarized light is reflected at a 90 degree angle while P-polarized light is transmitted. Since joining after the dielectric coating on the prism hypotenuse, endurance and polarization accuracy is excellent.
