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.
Just like high dollar machines (Trotec, Epilog) the lens is glued into a holder. Eliminating lens distortion from tightening it between two pieces of aluminum.
When combined with the K40 air Nozzle your lens will last longer, and finding the perfect focal distance is as easy as grabbing a quarter.
