Abstract

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 (90) according to a sign to be marked. A set of deflection means (30) for rearranging the laser beams (90) into a desired array of laser beams (90) is provided, the set of deflection means (30) comprises at least two deflection means (33a-i, 34a-i) per laser beam (90), in particular at least two mapping mirrors (33a-i, 34a-i) or at least one optical waveguide and one lens per laser beam (90a-i), and each deflection means (33a-i, 34a-i) is individually adjustable in its deflection direction and/or individually shiftable.
