Polarizing cube beamsplitters split randomly
polarized beams into two orthogonal, linearly
polarized components: S-polarized light is reflected
at a 90 deg 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 the prisms.
A multi-layer antireflective coating has been applied to
each face of the beamsplitter in order to produce maximum
transmission efficiency.
