Corner Cubes, also known as Corner Cube Reflectors, Trihedral Retro-reflectors, Trihedral Prisms, or Corner Cube Retro-reflectors, are most commonly used for alignment because light is always reflected back towards the source.
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:
Standard sizes are listed below. Custom-made sizes and special materials are also available upon request.
