Laser Lens Holder Compatible with ULS X660

thingiverse

I wanted a shorter focal length lens for our Universal Laser systems laser cutter. The cost of the 2.5 inch lens assembly was prohibitive so we ordered a lens and mirror from Light Object and created a holder that fit into the laser carriage. I used a 18mm ZnSe Focus lens (F50.8mm) and the 20mm High quality Si Plated Reflection Mirror. After printing I mounted the optics carefully glued it into place. I had luck printing at .15mm and not using supports (had to do some sanding). Test cuts show it works very well. Produces a more crisp cut than the existing 4 inch lens. In the photos the circle is cut with the new lens and the piece beside which shows a slight bevel is done with the official 4 inch lens.
