K40 - Adjustable focus Head upgrade
This system offers 3/8 adjustable focus (up and down). With the factory bed you would need the 1.5 focal length lens and nozzle. K40 head adapter sold separate. Buy a Kit and save 20%!!! Focus lens comes with (glued into) the adjustable focus lens tube. Protect your investment. American Photonics Easy clean lens mount makes daily cleaning a snap.
