Difference between this F30130 laser module and another module kits in our store：

1. This one is fixed lens, that one is focusing lens.
2. Different appearance
3. This one features with modified laser air assist function, fan in lens can keep the lens clean, then keep the optical power stable. While that one has no this function.

Features:

1. Designed for Laser Engraver, 3D printer, CNC mill, Arduino project.
2. 5.5w optical power output, can be used on NEJE Master 2 machines. If your machine is 7w or 3500mw, then need to change the power supply to 12V 3A.
3. Fixed lens design, not focusing lens, change the object height to change the focus distance.
4. 30mm size, do not influence the engraving area of NEJE MASTER 2 machines.
5. Vision protection, no need to wear the goggles.
6. Modified laser air assist, with the fans in the laser module, the lens will keep clean and keep the optical power stable.
7.More Quiet, Intelligent drive adjust the cooling fan speed according laser temperature. the lower temperature, the lower noise.
8. 15000rpm double ball high speed fan, stronger heat dissipation performance
9. Built-in 60mm threaded copper core, heat dissipation grease, safety temperature control, 48hours age testing before shipping.
10. 2 Year warranty, We provided 2 years warranty, Please do not open dispute or leave negative feedback without communication.
