Dove Prism

Dove Prism Drawing

 

Dove Prism is a form of prism invented by H. W. Dove. It resembles half of a common Right-Angle Prism in which a ray entering parallel to hypotenuse face is reflected internally at that face and emerges parallel to its incident direction. One of the incident rays emerges along a continuation of its incident direction, and if the prism is rotated about that ray through some angle, the image rotates through twice that angle. A Dove Prism must be used in parallel light.

The Dove Prisms is used as an image rotator; the output of a Dove rotates at twice the angular rate of the rotation of the prism itself. This kind prism has another application. The prism is used as a retroreflector. For this application it perform as a Right-Angle Prism that is used 180˚ deflection.
