Feature: 1. MULTIPLE APPLICATIONS: Laser module can be used for laser cutting machine, laser engraving machine, CNC router, DIY laser, etc. 2. EYE PROTECTION: The laser is equipped with a protective cover to protect the user's eyes, and there is no need to wear additional protective glasses. At the same time prevents pets from grabbing the laser spot 3. DURABLE ALUMINUM MATERIAL: Made of good quality aluminum material, which is sturdy and durable. Fixed focus laser is no need to focus 4. ENSURE LONG TERM USING: Aviation aluminum TTL driver board come with cooling fan to ensure continuous long term work, you don't need to worry 5. ENGRAVABLE MATERIALS: Used for wood, bamboo, cardboard, plastic, leather, PCB board, aluminum oxide, non reflective plating and lacquered metal, nigrescent utility knife 6. CUTTABLE MATERIALS: Laser module is suitable for cutting cardboard, non woven fabric, veneer, acrylic, some thin plastic sheets 7. POWERFUL, ACCURATE, AND FAST: 0.06X0.06mm double compression condenser coupling technology makes engraving more powerful and accurate, and the engraving speed is 200% faster than other 3W lasers. High energy, cutting 8.5mm thick sheet at one time 8. WIDELY COMPATIBLE: The laser sintering temperature is 1200??, the engraving metal effect is better. The air hood can clean the smoke and dust and protect the lens from laser damage and energy attenuation. The transfer board is compatible with 95% of laser engravers on the market, including for ortur, for Neje, for twotree, etc. Specification: Item Type: Laser Engraver Module kit Product Model: M50 Product Working Voltage: 12V 3A Product Size: Approx. 44 x 52 x 118mm / 1.73 x 2.05 x 4.65in Spot Size: 0.08x0.15mm Cutting Speed: 40% Faster Cutting Wood: Approx. 10mm / 0.39in Laser Power: 10-11W Laser Wavelength: 450nm Sintering Temperature: 1000??-1100??

Package List: 1 x Laser Host1 x PCB Circuit Board1 x Fixed Focus Plate1 x Power Cord1 x Compatible Board1 x Connecting Wire1 x Wrench and Screw Note: 1. The laser emitted by the laser module is likely to hurt people's eyes, so don't look directly at its end face and wear proper safety glasses to prevent laserirradiation 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 adjustment of the current should be increased or decreased slowly so as not to damage the equipment.3. Keep the equipment working or stored in a dry environment. The dustproof level exceeds 10,000 to prevent the dust inside the lens from affecting the shape of the laser spot.4. Working at high temperature will increase the threshold current, reduce the conversion efficiency and accelerate the aging of the device.5. When the output power is higher than the specific parameters of its operation, the aging of the equipment will be accelerated.6. When the working temperature of the laser diode exceeds 70 degrees, please do a good job of heating to dissipate it.7. This laser module is an electrostatic sensitive device. Be sure to ground yourself or wear an static proof wrist strap before taking.
