Retro-Reflectors

Retro-Reflectors

Retro-reflectors, or corner cubes as they are sometimes called, have the property that light incident on the face of the prism is deviated by 180 degrees independently of its angle of incidence. This means that any light incident on the surface will be reflected back along the same path that it came from.


These retro-reflectors are extremely precise providing an exact 180 degree deviation within a 2arcsec tolerances. This enables them to be used for high precision applications or with lasers over very long distances. These “angle insensitive” mirrors have numerous uses in alignment and metrology. Our retro-reflectors come standard with a broadband AR coating on the face. Optional black paint protected silver may be specified for the legs.
