AENBUSLM Laser Module with Air Assit for Laser Cutter & Laser Engraver Machine,20W Output Power,Built in FAC,Ultra-Fine Compressed Spot CNC Carving DIY Laser Master - Class 4

The newly upgraded 20W laser module is powerful, the engraving speed is 6-7 times faster than the traditional laser module, and the engraving effect on stainless steel is better. The laser engraving is 3 to 4 times more accurate than the traditional laser module, and the conversion speed is faster and more accurate. The precise power and laser power are calculated according to international standards, and the actual power is normal. Real power.
