Dove prism is a type of reflective prism, shaped from a truncated right-angle prism. Dove prism don’t change the direction of the input beam. When rotating the dove prisms through the longitudinal axis, it will rotate the image by twice the angle. A Dove prism is used to rotate, invert, or retroreflect an image, depending on the prism's rotation angle and the surface through which the light enters the prism. Dove prisms are often used in the fields of astronomy and interferometry applications.

Hangzhou Shalom EO offer the dove prisms made of BK7 optical glass, and they could be offered with uncoated, anti-reflection coated diagonal faces, or with aluminized diagonal faces.
