Getting down
to 0.08mm is going to be interesting, what with
beam-scatter and fluorescence. And I really don't like the idea of
using a focus-finder to set it up... viewing a laser through a
magnifying lens seems like a really dumb idea to me, even with
safety goggles.
This is something that I'd probably try to use a video camera with a
good macro lens and appropriate filter to adjust, so that you don't have
to worry about directly viewing the laser beam.
