Corner Cube Retroreflectors are triangular prisms consisted of three right angles of 90 degrees. Reflected beam has a characteristic of inevitably returning in the direction of the incoming optical axis. The accuracy is shown with angular deviation (parallelism) between input and output beams. It depends on the mutual perpendicularity of the trihedral surfaces. Using this characteristic they are often used in survey equipment. Processing from fused silica as well as optical glass is available upon your request.Be used in the localizers of missiles and satellites.
