This is a laser head with air-assist . The laser head is capable of hosting a 15mm/18mm diameter focus lens and a 20mm diameter reflection mirror. With the O-ring in the lens holder, the laser head now can install a 15mm diameter focus lens.

Easy swap-out for stock 40W K40 head
This head was a perfect purchase for my 40W (K40) machine. I thought I would have to modify things to line up with the new head and modify to install it. But that was not the case (wonderful surprise). I unscrewed the old head to remove it, and installed the new one right in the same mounting hole. And the laser opening (where the laser enters) was at the same exact height position as the old one. It just took a couple minutes to remove the old and install the new. And with an upgraded 18mm lens, this was a terrific inexpensive upgrade to my machine. Highly recommend!

Don't buy!
Terribly made. The screw that's suppose to fasten the nozzle to the lens holder can't be screwed in because the hole is too shallow.

18 mm laser head with air assist
I primarily use my k40 for engraving acrylic for edge lit lamps. I can't even tell you how much improvement this upgrade has made. It's incredible. I'm able to turn down my engraving power by 20 to 25% to get the same results. I also recommend the 18mm lens and a 950gph air pump for the air assist. You won't be disappointed.
