Description

Dove prism has 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 prism with collimated light. The top surface of dove prism is ground and the longest length (specified by dimension B) features an unbeveled sharp edge.
