Beam Splitter Plate

The common Beam splitters are used to split or combine laser beam. However Polarization BeamSplitters are used to split or combine two perpendicular polarization laser beam. The performance of beamsplitters is mainly dependent on the coating specifications.

Beam Splitter Cube

ube beamsplitters are constructed by cementing two precision right angle prism together with appropriate interference coating on the hypotenuse surface. The absorption loss to the coating is minimal transmission and reflection approach 50% (average) though output is partially polarized. If polarization sensitivity is critical to your online_ordering, we recommended that you select from our Polarization Cube Beamsplitter or Non-polarization Cube Beamsplitter.

Other BeamSplitter

Koster Prism
This special Beam Splitter is made of two special designed prisms. The cemented surface of one prism is beam splitter coating. The Prism enables splitting beam of light per two beams parallel to each other, and parallel to the input beam with high accurate. The distance between two output beams can be different for different prism size, but, shall be at least 4 times of beam size. The two-split beams have the same optical path.
Parallel Splitting Prism
This special Beam Splitter is made of two special designed prisms. The cemented surface of one prism is beam splitter coating. The Prism enables splitting beam of light per two beams parallel to each other, and parallel to the input beam with high accurate. The distance between two output beams can be different for different prism size, but, shall be at least 4 times of beam size. The two-split beams have the same optical path.

Beam-Splitting Prism
This special prism consists of one Right Angle prism and one Rhomboid Prism. The hypotenuse surface of the Right Angle Prism is beam-splitting coated and cemented to the Rhomboid Prism. The two split output beams are parallel to each other, and perpendicular to the input beam at high accurate. Distance of two-output beam can be different by changing the length of the rhomboid prism. The optical path of the two-split beams is different
