14DOP-1-2 Dove Prisms
Description
Dove Prisms are reflective prisms specifically designed for image rotation applications. They are shaped from a truncated right-angle prism, and 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.
As a result, the image passing through the prism is inverted or flipped, and its handedness is changed to the opposite sense. Dove prisms are ideal for image rotation and are commonly used in various optical setups where image orientation needs to be changed. They are available in different materials, and dielectric coatings can be applied upon request for tailored optical performance.

Frequently Asked Questions
A dove prism is a type of reflective prism that is used to invert an image.
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.
The dimensions of the dove prisms available are 21.1 × 5.0 × 5.0 mm and 42.3 × 10.0 × 10.0 mm.
The material used for the dove prisms is BK7 and UVFS.
