Beamsplitter

Polarizing cube beamsplitters split randomly polarized beams into two otehogonal, linearly, polarized compoments, S-polarized light is reflected at a 90° while P-polarized light is transmitted. Each beamsplitter comsists of a pair of percision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of prisms.

Description Of Polarising Cube BeamSplitters

Polarization Cube Beamsplitter

Polarizing Cube beamsplitters split randomly polarized beams into two orthogonal, linearly, polarized components, S-polarized light is reflected at 90° 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.

High Powe Cube Polarization Beamsplitter

High power polarization beamsplitter can be fabricated by Ecoptik (also known as BRD Optical).  Same as the above, it uses precision optical contacted technology which makes it has a high laser damage threshold.

High Damage Threshold>500MV/cm2

Transmission >96% @ Central Wavelength

Extinction Ratio>1000:1
