Corner Cube Retro-Reflector

Retro-reflector, also called corner cube, directs light that enters the prism back in the same direction. The reflection is relatively insensitive to the orientation of the prism. Retroreflector is the choice when the angle of incidence of a light cannot be precisely controlled.


- Precise 180° reflection
- No need to precisely align the prism
- Up to 1 arc second accuracy

The reflecting surfaces of this retro-reflector can be left uncoated or over coated with protective metal coating. The entrance/exit surface is anti reflection coated (AR coating).
