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. |

rhomboid prism can produce a lateral displacement between input and
output beam, and also the output image is reversed. Roof rhomboid
prism is always used in stereoscopic system and periscope system. |
