Polarization Beamsplitter Cube (PBC)
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.
