Advantages:

    Dove Prism resembles half of a common right-angle prism in which a ray entering parallel to  hypotenuse face is reflected internally at that face and emerges parallel to its incident direction. One of the incident rays emerges along a continuation of its incident direction,  and if the prism is rotated about  that ray through some angle,  the image rotates through twice that angle. A Dove Prism must be used in parallel light.

Applications: 

• Rotator. Dove Prism can rotate an image but without deviating the beam.  And when the prism  is rotated about  the input parallel ray through some angle,  the image rotates through twice that angle.  It is very important that the application must be used with parallel or collimated beam and the large square reflective surface should be kept very clean.
• Retroreflector.  For this application it perform as a right-angle prism that is used 180 deflection.

Specification:

*  Other sizes, and coatings are available upon requirements.
