That is a new part that Opt just came out with for the XT8 laser. The one I have is a prototype, but it works very well. It pretty much keeps all the reflected light down at work level. It fits over the end of their air nozzles, so it would probably fit onto most of their lasers.

Hi Ryan, The laser rod clamps are bolted tot he universal adapter plate (there are a couple of convenient tapped holes there already), and all the rest of the laser mounting hardware is metal so it all conducts through to the Z stage which is chassis grounded several ways, the best being the spindle wiring. So all I have to do is attach the magnet wire from the touchplate somewhere on the machine's chassis (i like the rotary unit because its got lots of steel) and then the laser touch rod or the spindle will trip the touch plate. I plan on added a 3D probe soon, and I will probably just wire the touchplate ground to chassis so that I don't have to drag the magnet and wire for it around.
