Product Description

Corner Cube Retro-Reflectors 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 orientation of the retro-reflector, within acceptance angle limitations.

Why is it called "Corner Cube"? Imagine a knife cutting diagonally across a square block of glass and then the "three-sided pyramid" is further cut with a cylinder. The diameter of the cutting cylinder determines the size of the Corner Cube Lens:

For applications in which either the acceptance angle for TIR is exceeded, or the reflecting surfaces cannot be kept sufficiently clean for TIR, a metal or dielectric coating can be applied to the reflecting surfaces.

Antireflection coated entrance and exit faces are also available.
