30W Laser Moudle Feature：

– Designed for Laser Engraver, 3D printer, CNC mill, arduino project.
– 7.5W Optical power output, 4mm plywood from 1 pass(speed 100), Able to engrave stainless steel, but it needs good focus adjustment.
– More Safety, Built-in protective glass to protect eyes! Even without wearing protective glasses, the operation is more comfortable.
– More Quiet, Intelligent drive adjust the cooling fan speed according laser temperature.
– Easy use, Digital PWM wave pulse signal generator adjustable frequency duty cycle board for neje laser module.
– slidable mounting fixture is provided for easy adjustment of focus.
