Rhomboid Prism

Rhomboid 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.
