At the risk of risky thread hi-jacking, does anyone have suggestions
for the optics and lenses on a "nearly submicron" laser cutter? I am
putting together what will eventually be an open source project
running LinuxCNC, but I am somewhat shaky on how to make sure I get a
spot size on the order of 1 to 10 microns (ok, maybe up to 20). Any
takers ?
