Polarization Beamsplitter Cube can separate a laser beam
into two different polarization beams, which can be used as
polarizer, beamsplitter or polarization beam combiner. The
output beam, which is parallel to input beam is called the
p-polarized beam, while the orthogonal output beam is
defined as the s-polarized beam.
