Marking apparatus with a plurality of lasers, deflection means and telescopic means for each laser beam

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 according to a sign to be marked. The marking apparatus is provided with a set of deflection means (30) for directing the laser beams (90) toward the object to be marked, wherein a set of telescopic means (40) comprising at least one telescopic means (40a-i) per laser beam (90a-i) is provided, and each telescopic means (40a-i) is adjustable for individually setting a focal length of the respective laser beam (90a-i).
