Retroreflector Prisms
Retroreflector prism has 3 mirror surfaces making angles of 90° to each other juxtaposed to form the corner of a cube with the entrance face perpendicular to cube diagonal. This retroreflector, also called trihedral retroreflector or corner cube reflector has the property that any ray entering the effective aperture will be reflected and emerge from the entrance/exit face parallel to itself, but with opposite direction of propagation. An incident beam, exactly filling the effective aperture, is reflected exactly back on itself. These properties are, within acceptance angle limits, independent of the orientation of the retroreflector. Retroreflectors therefore find frequent application in situations where orientation is difficult or impossible to control, and where a mirror would therefore be unsatisfactory. The retroreflector, like the right angle prism, based on the principle of total internal reflection (TIR). As a result, it also has very high transmission.
