how to make pencil thin beams

That was a matt polak special. not my idea. it however works real well. Still want to put a spatial filter in just cuz.

Next projector is the single mode one using logsquared's optics design, 506 scanners. Want to make it portable so I can bring it to work and program at lunch

Love the wood panels - that's what I call classy!

I did that on a laser cutter. it's cherry wood. I also moved the final expander back it made a difference in the final beam size.
