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. Regularly cleaned lenses last longer and perform better. Traditional lens mounting where threaded tubes hold your your lens tight work great for glass optics, but are terrible for soft ZnSe. The delicate crystal structure of ZnSe should be suspended by gluing. All the best laser engraving machine manufactures know this. And now American Photonics has brought this technology to your Chinese designed machine.
