Product Description
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. The Dove prism is named for its inventor, Heinrich Wilhelm Dove. 
21
A beam of light travelling parallel to the longitudinal axis, 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 (mirrored), and because only one reflection takes place, the image is also inverted but not laterally transposed.Uncoated dove prisms have an unusual and very interesting characteristic – if you look through the prism and rotate it around a longitudinal axis, the image rotates through twice the angle the prism rotates through. 
23
Refraction at the entrance and exit surfaces results in substantial image astigmatism when used in convergent light. Thus the Dove prism is used almost exclusively for images appearing at infinity.If the flat hypotenuse surface of a Dove prism is cut into a roof shape, the result is an Amici roof prism.
24
Rotation

A reflection in one axis of a plane is always equivalent to a reflection and rotation in two other axes (with the angle between the source and image being twice the angle between the source and reflection axis of the prism). Thus, Dove prisms can be used to create beam rotators, which have applications in fields such as interferometry, astronomy, and pattern recognition.
