6. Instruccions de funcionament
6.1 Eye Protection and Laser Technology
The P9 M40 features a new filter eye protection acrylic design that filters 97% of ultraviolet light, allowing you and those around you to observe the laser engraving without needing goggles. The machine utilizes an upgraded high-performance fixed-focus laser with a focal spot area only 1/3 of ordinary lasers, combining precision engraving and high-energy cutting. The laser power is stable, and the newly upgraded ultra-fine compressed laser uses 4-fold lens group collimation focusing technology, reducing the laser focus area to 0.08*0.08mm. This high-density laser can cut 15mm thick wooden boards and black acrylic, and directly engrave mirror stainless steel and ceramics, achieving results comparable to a 100W CO₂ laser engraving machine.
