Abstract: The invention relates to an assembly and method for detecting laser radiation which hits a disc (20, 28) sealing an opening (16, 18) of an enclosure, wherein at least one sensor (22) detecting the radiation is aligned having the radiation sensitive region (24) thereof on a circumferential edge section (26) of the disc, which is designed to be radiation-conducting. In order to enable secure monitoring both of the disc and of the enclosure, without a plurality of sensors being required, according to the invention, the enclosure has two walls (12, 14) spaced apart from each other and having openings (16, 18) which are sealed by the disc (20), the disc (20, 28) is arranged between the walls at the edge and the sensor (22) is arranged having the sensitive region (24) thereof between the walls, spaced apart from the disc or within an opening of the disc.

Abstract: The laser beam optics for a robot link, wherein a first beam path of a first working laser beam is arranged on the longitudinal axis of the robot link, the first beam path is deflected at an end facing a workpiece into an axis-parallel second beam path, and a third beam path of a second working laser beam is axis-parallel to the first beam path in the robot link, have two optical elements arranged successively in one of the first and second beam paths of the first working laser beam. The two optical elements are transmissive for the first working laser beam in a transmission direction toward a workpiece and are adjusted relative to one another so as to compensate laser beam displacement of the first working laser beam. The second optical element arranged downstream receives the second working laser beam and reflects it toward the workpiece.
