Abstract
A device for processing a workpiece using a plurality of parallel laser beams includes a focusing optical system displaceable in a direction of an axis of symmetry configured to focus each of the plurality of parallel laser beams onto a common focusing plane, and wherein the plurality of laser beams include a first and a second laser beam pair, each containing two laser beams equidistant from the axis of symmetry. The device further includes a reflector assembly having at least two reflectors each having a plurality of reflection surfaces displaceable relative to one another in a direction of the axis of symmetry.
