I've been looking into Laser lenses and I noticed with engraving lenses, they normally try to focus a smudge into a dot. I've also noticed the 445nm lasers produce a bar, rather than a dot.
Is it possible to turn that bar into a dot, even it its only got a range of a couple of millimeters? I'm just imagining a wedge shaped crystal squishing the bar into a tiny square, but I don't really know what I'm talking about.
