1. laser, , ≥10,000 hours: 2. Precision lens, extremely small spot, Less than 0.05MM: 3. Air duct optimization, smoke blowing and anti-sticking, no need to wipe and easy to replace: 4. Liquid metal, super heat dissipation, reducing the laser by 8℃ at most: The use of new laser diodes and high-temperature glass lenses makes the laser more and reliable. LD adopts a non-removal cap multi-lens compression solution, which achieves no power loss and makes the energy more concentrated. Low temperature welding + liquid condensation welding assembly process, high thermal conductivity, efficient heat dissipation and No attenuation for more than 10,000 hours. The micro-laser supports engraving/cutting/punching materials: metal (stainless steel, copper, aluminum, etc.), tiles, wood, bamboo, stone products, acrylic fabrics, leather, PVC, plastic, paper products, horns and other handicrafts. Blue light output power: 5W±5% Blue light wavelength: 455nm±5nm Focus position (fixed focus): 27mm±0.2mm Focus size: 0.035mmx0.048mm Laser level: Level 4 Power board input voltage: DC 12V Control signal: TTL/PWM (0-5V) Trigger mode: off/5V on Modulation frequency: Less than 5KHz Heat dissipation: Quick air cooling Recommended working environment temperature: -30℃-40℃ Color: As Shown Material: Plastic+Metal Package Contents: 1 x Laser Cutting Fixed Focus Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
