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