     Polarization Cube Beamsplitter
Home >> Polarizing beam splitter >> Polarization Cube Beamsplitter 

Polarizing Cube Beamsplitters 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 dielectric coating on the hypotenuse of one of prisms.
