Laser Retro-Reflector
thingiverse
A Lunar Laser Retro-Reflector Replica is a precise imitation of the device that reflects laser beams back to Earth from space. The retro-reflector, also known as a cataphote or retro-flector, sends light signals straight back to their source with minimal scattering. I watched Adam Savage build his replica and I wanted to learn more about this technology. A paper I found provided additional information including exact dimensions for the reflectors, which I used in my version of the laser retro-reflector. The device is based on 12.7mm reflectors that are 0.5 inches thick.
