Dove Prism
Dove Prisms are precision optical prisms designed for image rotation and beam manipulation applications. Using total internal reflection (TIR), Dove prisms rotate images without introducing significant optical loss. Chenyu Optics manufactures Dove prisms in BK7, fused silica and UV fused silica with custom dimensions and coatings.
Dove Prism Overview
Dove Prisms are precision optical prisms designed for image rotation and beam manipulation applications. By utilizing total internal reflection (TIR), Dove prisms rotate images without introducing significant optical loss.
They are widely used in imaging systems, laser optics, telescopes and precision optical instruments where controlled image orientation is required. Rotating the prism about its optical axis rotates the transmitted image at twice the prism rotation rate.
Chenyu Optics supports custom Dove prism manufacturing according to customer drawings, including custom length, aperture, angle tolerance and coating design for prototype and repeat production.

Dove Prism FAQ
What does a Dove prism do?
A Dove prism rotates an image by using total internal reflection. The rotation angle depends on the physical rotation of the prism around its optical axis.
Can Dove prisms be used for laser applications?
Yes. Dove prisms are commonly used in laser beam manipulation and alignment systems.
Which materials are available for Dove prisms?
Common materials include BK7, fused silica and UV fused silica, selected according to wavelength requirements.
Are AR coatings required for Dove prisms?
AR coatings are optional. TIR surfaces normally do not require coatings, while entrance and exit surfaces may benefit from AR coatings.
