Mehrkopf-Lasergravuranlage

摘要

The installation includes a laser unit (1), at least two illumination heads (15,16) with their individual optical elements and beam deflection systems which direct a part of the laser beam energy as an engraving beam (S1,S2) onto a region (F1,F2) of a workpiece surface, and control unit (9). The installation is characterised by the fact that each illumination head is provided with a controlled fast optical switch (6,7) which either passes or blocks the corresponding part of the laser beam energy, and that the switches are controllable independently of one another by the control unit (9). Also claimed is a corresponding fast optical switch.
