Title: Corner cube side decrease of amplitude of beam of light

Abstract: An apparatus in one example comprises a corner cube that comprises a first side, a second side, and a third side that cooperate to retro-reflect an incoming beam of light and output an outgoing beam of light. One or more of the first side, the second side, and the third side of the corner cube serve to contribute substantially to a decrease of over twenty percent in an amplitude of the outgoing beam of light relative to an amplitude of the incoming beam of light.
