Product Description

N-BK7 Polarizing Beamsplitter Cube(PBS)

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.
