Dove Prisms rotate an image without deviating the beam in such a way that the image rotates at twice the angular rate of the prism. Holmarc offers Dove prisms with single layer anti-reflection coating on end faces. The hypotenuse face has total internal reflection, hence does not require AR coating.
Uncoated prisms are also available. Broadband multi-layer AR coating on faces can be done on custom basis.
