Laser Tight Beams

The prototype 1 dimension collimator. The plastic has a bit of flex and the print quality was less than perfect. The orthogonal divergence improves significantly, approaching the parallel axis divergence creates a square beam profile. Rough measurements look like were under 1mrad full beam width, both directions. (I was bouncing the beam off parallel mirrors to measure)

Waiting for some parts for red and blue, keep revising the collimator for laser cut aluminum parts. Got a new workshop coming soon, might make a bunch of lasers I dunno.

Thanks for reading, more pics and developments coming soon.
