Optical Variable Effects for Minting Applications

The appearance of polished gold and silver has always been attractive to the human eye. The high reflectivity of these surfaces naturally makes them strong candidates for optical designs that are based purely on reflective optics. When circular grooves are scribed into metal surfaces, some very interesting optical effects can be observed, and in some cases light beams will appear to come out of the surface. Other light beams will appear to go into the surface. Through clever design and orientation of these scribed regions, the appearance of interesting optical effects can be generated.
