Corner Cube Retroflector

Corner Cube retroreflectors use three mutually orthogonal reflectors to retro-reflect any ray that lands on it over a wide range of incident angles. This makes it very useful in applications where precise alignment is difficult to achieve, where vibration is present, or where the retroreflector must be moved, for example.

Corner cube prism holders are available upon request.
