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.
Images passing through the prism are flipped, and because only
one reflection takes place, the image's handedness is changed to
the opposite sense. Dove prisms have an interesting property
that when they are rotated along their longitudinal axis, the
transmitted image rotates at twice the rate of the prism. It is
very important that the application must be used with parallel or
collimated beam and the large square reflective surface should be
kept very clean. Another application is used as a retroreflector.
For this application it performs as a right-angle prism.
