Dove Prisms

Optics >>> Prisms >> Dove Prisms

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.
