MARKING APPARATUS COMPRISING A PLURALITY OF LASERS, AND DEFLECTION MEANS AND TELESCOPIC MEANS FOR EACH LASER

摘要

The invention relates to a marking apparatus for marking an object with laser light, comprising a plurality of lasers and a control unit for individually activating each of the lasers to emit a laser beam (90a-90i) according to a sign to be marked. A set of deflection means (30) for directing the laser beams (90a-90i) toward the object to be marked is provided, a set of telescopic means (40) comprising at least one telescopic means (40a-40i) per laser beam (90a-90i) is provided, and each telescopic means (40a-40i) is adjustable for individually setting a focal length of the respective laser beam (90a-90i).
