Corner Cube Retroreflectors

Short Description:

A corner cube, also known as a retroreflector, is an optical component with the unique ability to return an incoming beam of light directly towards its point of origin regardless of the beam’s angle of entry. This property makes this prism type ideal for a wide variety of applications, such as laser resonator cavities, land surveying, ground based range-finding, satellite communications and space vehicle docking.

Specifications

Corner Cube prism has three mutually perpendicular surfaces and a hypotenuse face.  It operates on the principle of total internal reflection(TIR).  A beam entering the effective aperture is reflected by the three roof surfaces and emerges from the entrance/exit surface parallel to itself.  This property is independent of direction of the retro-reflector, within acceptance angle limitations.  For applications in which either the acceptance angle for TIR is exceeded, or the reflecting surfaces can not be kept sufficiently clean for TIR, a metal or dielectric coating can be applied to the reflecting surfaces.
