Here’s the link to the manufacturer’s website: https://optlasersgrav.com/cnc-laser-upgrade-kits/plh3d-15w-engraving-laser-head-universal-kit
Definitely not cheap and I wonder how it compares in performance to the NEJE 2 diode laser that claims the same optical output. Here’s the link for the offer on Amazon: https://smile.amazon.com/dp/B0915WF5Z4?ref=vse_pfo_vwdp
Decimal point misplaced for my needs 
Thanks for info

This device combines 3 laser diodes and looks very precisely built. I think the NEJE 2 has 2 diodes only. I would expect that this Opt Laser Module is much stronger than the neje, but it has a shorter focus distance which limits the cutting performance for thick material.
