Cube Beamsplitter

Non-Polarizing Cube Beamsplitter

Non-polarizing Cube Beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a metallic-dielectric coating on the hypotenuse of one of the prisms. The low polarization dependence of the metallic–dielectric coating allows the transmission and reflection for S and P-polarization states to be within 5% of each other. They will not change the state of polarization of the incident beam.

Polarizing Cube Beamsplitter

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