BK7 and UVFS Corner Cube Retroreflector Prism are designed to deviate incident light by 180 degrees independently of an angle of incidence. These corner cube prism have three mirror surfaces with angles at 90° to each other, juxtaposed to form the corner of a cube with the entrance face perpendicular to the cube's diagonal.

Description Of Corner Cube Retroreflector Prism

A corner cube retroreflector, also known as a CCR or trihedral optical prism, is an optical structure that consists of three adjacent, mutually-orthogonal plane-reflecting surfaces which form the corner of a cube. The corner cube reflects an incident ray at a specific angle, independent of the prism and beam orientations.
