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.
