Invented by H.W. Dove, Dove Prisms are also known Reversion
prisms. When the prism is rotated about its length axis,
the image viewed through the prism rotates at twice the prism
rotation rate. This is an unusual and sometimes useful
property for special applications. Entry and exit faces
are anti-reflection coated.
