The Dove Prism is also called Image Rotator. The prism rotates the image without changing the direction of the input beam, which is parallel to hypotenuse. Rotation of the prisms in relation to the subject causes double rotations of the image. Dove Prism should be used in the parallel beam. A-STAR also offers Dove prisms AR coated on the hypotenuse for use in beam-folding applications. As the S1 and S2 sides are used in a total internal reflection (TIR) manner, it is extremely important to keep these two surfaces clean.
