Beamsplitters
Beamsplitter Plates
Beam splitter plates are primarily used to split or re-combine a beam of light,
especially in high power lasers.
When using beam splitter plates, it is important to bear in mind that the two partial
beams travel different optical paths.
The optical paths depend on the incident angle and the thickness of the plates. The beam
can be shifted.

Polarization Beamsplitter (PBS)
The prisms function as polarizers, beam splitters or beam combiners.
The output beam which is parallel to the input beam is called the p-polarized beam,
while the orthogonal output beam is defined as s-polarized.
