Laser protection arrangement with a safety cutoff comprising a passive laser protection wall which stores the radiation energy of impinging radiation of a laser of a laser material processing installation, a laser protection foil which causes a detectable change when struck by laser radiation and which is arranged in front in direction of the laser radiation, and at least one sensor which is connected to the laser by a threshold switch in order to switch off the laser when the received detector signal exceeds or falls below a threshold value.

Laser protection arrangement with safety cutoff

An arrangement for machining workpieces by a laser, particularly for cutting, perforating, notching, engraving, drilling and inscribing workpieces with three-dimensional structures of different sizes. The laser beam is directed to the workpiece, which is fixed on a holding device, by means of a robot-guided articulated mirror arm and a laser scanner. The laser beam is guided by a coordinated time-controlled and position-controlled deflection of the articulated mirror arm and of the mirror elements of the laser scanner.
