Deviating Penta Prisms

Knight Optical supply custom deviation prisms that cover the visual and NIR range.

Deviation prisms are an optical component that will redirect a light beam into another known angle relative to the incoming beam. The penta-prism is a deviation prism which is used in cameras with a movable mirror that bends the beam vertical onto the focus graticule. The penta-prism provides a 90° deviation of the beam from the focus plane and, via an eyepiece, the user can aim the camera along the same axis as the beam that is focussed onto the detector, electronic or wet film. Deviations through other angles can be accomplished using, for example, abbe constant deviation, littrow, and wadsworth prisms.

Knight Optical supply high quality custom deviation prisms made to our design or to your custom specification. Every component is individually tested by our highly skilled technicians using our Trioptics Prism Master capable of 3 arc seconds accuracy to ensure all components meet our high quality standards.
