4.3 Beam Scanning System

Scanning system consists of the Scanalone Board, Scanner, and focusing objective

(Fig.4.8). Scanner with objective are mounted on the front panel of the laser and do not require
any alignments. Scanner is powered by the se/-15VDC power supply. The board is
connected to the scanner, laser Q-SW control, PLC, 24VDC power supply, and via USB cable to
the computer. Optimized for a high speed marking, M100LFG software transforms the required
printing information into the set of command downloaded into the Scanalone Board that controls
both the scanner and the laser

.
