I’ve been struggling to find an answer for this one and was hoping you could help.
Is there any optimal distance between the final mirror (3rd mirror) and the lens itself? I have just bought some new lenses (50.8mm and 38.1mm II-VI’s) and a short nozzle from cloudray and wanted to know.
Everyone talks about the distance between the actual lens and it’s focal length to the material you’re cutting but I’ve never read about the distance between the final mirror and the lens…
Does it make a difference??
