I was wondering if anyone had ever tried this or if anyone had any good ideas for what to use . I am going to make an attempt using a couple different methods I will report back.
I’ve done glass engraving with a co2 laser before and glass behaves differently to most materials. The engraving forms multiple small frits rather than a clean engrave like with pmma for example. For most engravings the quality is still very good. However we are taking about an incredibly small scale. A co2 laser dot is around 0.1mm. So you would need a shorter wavelength to achieve anything high resolution enough on a glass surface that small. You are probably talking 532 or even UV marking machines.I was wondering if anyone had ever tried this or if anyone had any good ideas for what to use .

You sure would. It’s one of those problems that are not impossible but practically difficult. Its a case of microprocessing. I’m wondering whether a single mode 405nm engraver will have enough power density and clarity to achieve a engraving of that sort of scale. The issue is cheap engravers generally are not as well calibrated to allow for such microengraving. Not unless you can get a galvo based system.This is a pretty neat idea. However, the area of the collimated beam coming out of the lens is much smaller than the actual lens so you'd really need some precision etching. This idea may be more feasible with a large window non-collimated diode.
