Description

Dove Prism is a kind of prism invented by H. W. Dove. It resembles half of a common Right-Angle Prism in which an incident ray parallel to hypotenuse face is reflected internally at that face and emerges parallel to its incident direction. If the prism is rotated through some angle to the incident ray, the image rotates through twice that angle. A Dove prism just can be used for parallel light. The prism can also used as a retroreflector. For this application it perform as a Right-Angle prism that is used for**0 degree deflection, and after two times reflection, the image became ingenuous.
