Here the problem was getting a point light source (20 mils) with a dispersion angle of about 20 degrees. I'm using an original crater lamp now, but hate to demonstrate it, since there are very few of these around. Couldn't a bright LED be used with 4 parallel mirrors and a hole 20 mils in diameter?

Instead of 4 parallel mirrors I should think an internally polished cylinder (or large converging lens) would be better.
However why not simply saw off the top of a bright LED and then polish the resulting flat emitting surface? Wouldn't the result then be an instant 'crater lamp' ?
