The beam reflection is achieved either through total internal reflection or by mirror coating on the rear surface of the retro reflector . An Incident beam filling the effective aperture, is reflected exactly back on itself.
The Protective Al2 coating can be given to the rear reflecting Surface to avoid total internal reflection failure at high incident Angle.
