445nm Laser Engraving Module 2W (2000mW) 12V with PWM/TTL

In addition to being used as a laser engraving module, this product can also be used in many professional fields: stage lighting, industrial production, information communication, medical beauty, laser measurement, military, etc.

Features
1. The laser spot is uniform and bright, the divergence angle is low, and the collimation is good.
2. The temperature control, drive, and laser are fully integrated. The internal structure is compact, and the external power supply is available.
3. This laser module has reliable stability after tests of high/low temperature and vibration impact. When the temperature is in the range of -10℃ ~ 70℃, it can work continuously for 24 hours a day.
4. Precision scientific heat dissipation, two-way temperature control, and perfect temperature protection can extend the useful life of the laser module as much as possible.
