Corner Cube Reflector

Corner Cube Retro Reflector operates on the principle of Total Internal Reflection (TIR). An incident beam will be reflected parallel to itself by the three roof surfaces. The reflection is insensitive to the incident angle, even when the incident beam enters the prism off normal axis, there will still be a strict 180deg reflection.
