Customized or Standard Optical Dove Prism

Product Description

Dove prismshave an unusual and very interesting characteristic - if you look through the prism and rotate it around a longitudinal axis, the image rotates through twice the angle through which the dove prism itself rotates. For optimal peformance, use dove prisms with collimated light. The top surface of each Dove Prism is ground and the longest length (specified by dimension B) features an unbeveled sharp edge.
