PowerLine E QS Series are air-cooled Class 4 laser marking sub-systems ideal for applications where mark quality, aesthetics and legibility are critical. They combine a diode-pumped, green solid-state laser with high-performance scan¬ning and beam delivery optics, drive electronics, and powerful control software to yield a fast, flexible, and accurate marking platform. The included Visual Laser Marker (VLM) applications software enables mark artwork to be transferred directly from a computer to the marker, and supports a number of sophisti¬cated functions, including marking-on-the-fly and 3D marking, and marking of variable data (bar codes, serial numbers).
