CORNER CUBE RETROREFLECTOR Download PDF document

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: corner cube

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.

NOTES!  
Every edge of these prisms is chamfered (beveled) for chipping prevention. The dimensions of these prisms are values not including chamfer.
Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
