High Accuracy Corner Cube Prism

Corner Cube Prism also called  Retroreflector. It has three mutually perpendicular surfaces and a hypotenuse face. Light entering through the hypotenuse is reflected by each of the three surfaces in turn and will emerge through the hypotenuse face parallel to the entering beam regardless of the orientation of the incident beam. For its special performance,it is often used to the distance measurement, optical signal process and laser.
