I’m looking for a 20-50x. Microscope objective with a working distance like 1-2cm. They are available for like 2.5k but yea I don’t have money like that. I was wondering what people use for laser cutters. Do they have similar distances? I’m using it for my PhD bouncing a focused dye laser off a 0.1mm facet on a crystal so I need to focus the laser down on that surface.
anybody have a solution for this kind of extreme focus at a distance? The laser is tem00 and really high quality. The starting size it about 1mm. Hence thinking 20x should get me there with some slack.
