Typical designs are:
|Order No.||Functional Drawing||Photo||Description|
|Right Angle Prisms||Simplest and most cost effective prism for 90° beam deviation. Also for 180° deviation with lateral displacement. At 180° reflection, the image is reversed. The accuracy of the 90° deviation angle depends on the orientation of the prism – the beam can be directed in both planes. At 180° reflection, the beam can only be directed in the plane perpendicular to the lateral deviation. The 180° angle is determined by the precision of the prism.|
|Dove Prisms||Image inversion without angular or lateral beam deviation.|
|Amici Roof Prisms||Same 90° beam deviation function as the right angle prism, except that the image is mirrored.|
|Pentaprisms||Designed for a beam deviation of 90°. The image has the opposite orientation to the right angled prism. The 90° deviation angle is determined by the precision of the prism – the beam can not be directed by the orientation of the prism into the 90° direction.|
|Beamsplitter Pentaprisms||A variation of the pentaprism with two output beams. The second beam is neither deflected nor moved laterally. The power of the input beam is split between the two output beams.|
|Corner Cube Reflector||Deflects a beam by 180°, regardless of the orientation of the optic. A beam that is more narrow than the entrance pupil and not centered on the optic is shifted laterally. The image is inverted and mirrored. Retroreflectors can be solid or hollow.|
|Wedge Prisms||Essentially a window with non-parallel optical surfaces. The angle between the surfaces determines the angular deviation. Used for beam direction. A beam that enters with normal incidence can be directed by turning the prism over the lateral surface of a cone.|
