CaF2 Corner Cube Retro-Reflector Prism
Description
Corner Cube Retro-Reflectors operate 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.
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.

Yes, a metal or dielectric coating can be applied to the reflecting surfaces of a Corner Cube Retro-Reflector for applications in which either the acceptance angle for TIR is exceeded, or the reflecting surfaces cannot be kept sufficiently clean for TIR.
A Corner Cube Retro-Reflector 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.
A CaF2 Corner Cube Retro-Reflector Prism is a type of prism that operates on the principle of total internal reflection (TIR) and reflects a beam of light back to its source.
The acceptance angle for TIR is the maximum angle at which light can enter the prism and still be reflected back to its source.
