Powerful 3500mW Engraving Laser Module 445nm with Adjustable Focus

This 445nm laser module is one of our most popular products, with high power, high stability, adjustable focus, and a cooling system. It can work continuously 24 hours a day, and you don't need to worry about heat dissipation. It has the imported diode, a small laser spot, a slight divergence angle, and good collimation. The scientific heat dissipation design, two-way temperature control, and perfect temperature protection function can prolong the life of the laser module as much as possible. Temperature control, driver, and laser are perfectly integrated - you only need to provide DC power.

This model is tested for high/low-temperature storage and vibration shock. If you're looking for a powerful engraving laser module, it's a cheap and reliable option.
