Beamsplitter Prisms

Conventional Polarizing Beamsplitter Cubes of broad band

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 cists of a pair of precision high tolerance right angle prisms cemented together with

a dielectric coating on the hypotenuse of one of prisms.
