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.

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.
