Optical Glass Dove Prism

A Dove prism is a type of reflective prism which is used to invert an image. Dove prisms are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face.dove prisms are ideal for image rotation.Dove Prisms have two application. One is creating an image inversion in beam input parallel to the base. Another application is used as a retroreflector. it perform as a right-angle prism. have an unusual and very interesting characteristic - if you look through the prism and rotate it around a longitudinal axis Images passing through the prism are flipped, and because only one reflection takes place
