Beamsplitter Plates

Beamsplitter plates are primarily used to split or re-combine a beam of light, especially in high power lasers. When using beamsplitter plates 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.
