Working principle
The laser beam is generated by a CO2 laser source and expanded by the beam expander, and
then sent to movable mirrors. Two galvanometer-operated mirrors deflect the expanded laser
beam, the mirrors steer the laser beam onto an optical lens which focuses the steered beam
onto the substrate.
The controller of the laser provides electrical power supply to the laser head required by the
CO2 laser source in order to generate the laser beam.
Using 7031 software, the computer inside the laser controller controls the galvanometer
mirrors. The marking is made by directing the beam in directions x and y according to the
message composition.
