ATOMSTACK M40 40W Universal Laser Module for Laser Engraving Machine Optical Power 5-5.5W

Specification:

Features: 
1. It can be used for laser cutting machine, laser engraving machine, CNC, DIY laser.
2. Laser protective cover: The laser is equipped with a protective cover to protect the eyes of the user without additional protective glasses. At the same time, prevent pets from catching the laser spot.
3. Made of aluminum, strong and durable.
4. Upgrade high-quality fixed-focus laser, no need to focus.
5. Aviation aluminum TTL driver board with cooling fan to ensure continuous operation for a long time.
6. Engravable materials: wood, bamboo, cardboard, plastic, leather, PCB board, aluminum oxide, non-reflective electroplating layer and lacquered metal, blackened utility knife.
7. Cutable materials: cardboard, non-woven fabric, veneer, acrylic, some thin plastic boards.
8. The 0.23x0.23mm ultra-thin laser focus makes the engraving stronger and more precise.
9. The transfer circuit board is compatible with 95% of the laser engraving machines on the market. Including Atomstack, ortur, Neje, twotree, etc.

Precautions:
1. The laser light emitted by the laser module may harm people's eyes, so do not look directly at its end face and wear appropriate safety glasses to prevent laser light from being irradiated when it is working.
2. The laser module requires a suitable laser driver (PCB). When the laser module is connected to the power supply, please set the output voltage to zero. The current adjustment should be increased or decreased slowly to avoid damage to the equipment.
3. Keep the equipment working or storing in a dry environment. The dustproof level exceeds one level to prevent the dust inside the lens from affecting the laser spot shape.
4. Working under high temperature will increase the threshold current, reduce the conversion efficiency, and accelerate the aging of the equipment.
5. When the output power is higher than its specific operating parameters, it will accelerate the aging of the equipment.
6. When the working temperature of the laser diode exceeds 70 degrees, please take measures to dissipate heat.
7. This laser module is an electrostatic sensitive device. Please make sure you are grounded or wear an anti-static wrist strap before taking it.
