Highlights

Professional Laser Module
Features 10W optical power output, it can cut 4mm plywood by 1 pass (speed 200), and cut 3mm black acrylic board by 1 pass. Also, it's able to engrave stainless steel, but it needs good focus adjustment. 
Designed for Laser Engraver, 3D printer, CNC mill, and Arduino project.
More Safety
Built-in protective glass to protect eyes! Even without wearing protective glasses, the operation is more comfortable.
Quieter
The intelligent drive adjusts the cooling fan speed according to laser temperature.
Easy to Use
Digital PWM wave pulse signal generator adjustable frequency duty cycle board is for NEJE laser module.
The slidable mounting fixture is provided for easy adjustment of focus.
