Abstract: A monitoring device (10) for a laser machining device (12) that has one or more laser beams (13) that are displaced along a predetermined adjustable trajectory (14, 16) along a workpiece (18) includes one or more sensors (20, 22) which monitor(s) the processing signal (24) of the machining process in a three-dimensional section (26). The one or more sensors (20, 22) activate an alarm device or interrupter (28) for the one or more laser beams (13) of the laser machining device (12) if the one or more process signals (24) in the section (26) exceed a predetermined threshold value or fall short of it, the one or more sensors (20, 22) being independent of the laser machining device (12).

Abstract: The invention relates to a device for shielding coherent electromagnetic radiation, especially laser radiation. The device comprises at least two partially converging faces (6, 7) between which two opposite openings (8, 9) are configured. The distance of the faces (6, 7) between the two openings (8, 9) varies to such an extent that the electromagnetic radiation is prevented from going from the one opening (8) straight through the other opening (9).

Abstract: The invention relates to a wall segment (10) for device, such as a cabin, a wall or a screen, protecting against laser beams from a laser source (38) and enclosing a work or effective zone, this wall segment comprising an inner wall (12) adjacent to the work or effective zone and an outer wall (14) parallel to the inner wall (12) and farther away from the work and effective zone than the inner wall (12). To activate an emergency OFF system to shut down the laser source or the processing machine, the inner and outer walls (12) and (14) resp. are metallic, for instance of iron or steel sheetmetal, the inner wall (12) being fitted at least on its side (18) facing the work or effective zone with a highly absorbent coating (16) and the side (22) of the outer wall (14) facing the inside wall (12) being of lower absorption.
