Custom Corner Cube Prisms

Corner cube prisms, also known as retroreflector prisms, are designed to reflect an incoming light beam back toward its source regardless of the incident angle within a certain range. This unique retroreflection function makes them ideal for laser ranging, surveying, alignment and optical measurement systems.

A corner cube prism consists of three mutually perpendicular reflecting surfaces. High angle accuracy and surface quality are essential for precise return beam performance.
