Detailed Product Description
Beamsplitter Plate/ Beam Splitter Plate
Beamsplitters are used to split or combine beam of light. Plates and cubes are the most common types.The performance of beamsplitters are mainly depended on the coating specifications. In selecting beamsplitters, the forms, coating, transmission and damage threshold should be considered.
Beamsplitter plates 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.
