Rhombic Prism

Rhombic Prism description

Rhombic Prism are used to display a beam laterally without changing it’sdirection. 

They are coated to transmit part of the beam and produce two parallel and displaced emerging beams. 
Can be coated to produce a polarizing beam separator. Coating design are per customer’s design according it is detailed application
Rhombic Prism can displace a laser beam without change the image orientation, the input beam is totally internal reflected by two 45degree faces and goes out from the output face. Then, a lateral displacement is produced. 

Higher transmission rate can be achieved by anti-reflective coating on the input and output faces. Rhomboid prism is always used in stereoscopic system and periscope system.

Currently we can make angle tolerance <5 arc seconds, total beam deviation <30 arc seconds. Large size is also available.
