道威棱镜

Dove Prisms are also known Reversionprisms, which is used to invert an image.Dove prisms are shaped from a truncated right-angle prism. A beam of lightentering one of the sloped faces of the prism undergoes total internalreflection from the inside of the longest (bottom) face and emerges from theopposite sloped face. Images passing through the prism are flipped, and becauseonly one reflection takes place, the image's handedness is changed to theopposite sense.
