Audited Supplier Dove prism
Named for its inventor Harting Dove, dove prisms (with antireflection coatings on the ends) completely invert an image by 180 degrees. If the prism is rotated about its axis the image will rotate at twice the rate of rotation of the prism. Dove prisms provide a convenient and precise method of rotating a beam. The long length and square profile makes them easy to mount in a cylindrical sleeve.
Dove prisms need to be used with collimated or near-collimated beams because of the very limited field of view. When used as an image inverting prism the hypotenuse face acts as a TIR surface and is therefore normally not coated. Therefore, it is important to keep this surface clean.
