Product Description

Optial Glass/Germanium/Fused Silica Coated/Uncoated Dove Prism

Invented by H.W. Dove, Dove Prisms are also known Reversion prisms.

CPG followed the base rule of the design to produce this kind of products, 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 making them useful in beam rotators, which have applications in fields such as interferometry, astronomy, and pattern recognition.

Usually Dove prisms are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image is inverted but not laterally transposed.

Considered the use, Dove Prisms are usually coated with anti-reflection layer and aluminum layer to provide more efficiency transmission. But sometimes dove prism will use as U-turn like pieces, for this application, we can get high accuracy better than with two pieces of reflecting mirrors.
