Broadband and Narrowband Non-Polarizing Plate Beamsplitters
Non-Polarizing Plate Beamsplitters can be used with high power laser. When using beamsplitter plates, it is important to bear in mind that the two partial beams travel different optical paths. And the optical paths depend on the incident angle and the thickness of plates.
