I built a prototype contraption to cast an angled slice of light onto a little platform. I didn't bother much with focus tonight, I just wanted to get the mirrored field black. Turns out when you're super close, the coin reflects the inside of the box lid, but some black felt and painter's tape did the trick. I definitely need to get the light distance, filtering, and glare figured out.
For all the deficiencies of the prototype, it did get the fields acceptably black and the devices relatively silver.
