The measuring device for a laser beam processing device, is claimed, where a ring-shaped laser beam (6) is produced by the laser beam processing device for processing a component in a processing area and an optical element (16) is arranged in an optical path of the laser beam and deflects the laser beam to a sensor (24). The optical element is arranged in the processing area that comprises a reflection surface (20), which deflects the ring-shaped laser beam to the sensor. The measuring device for a laser beam processing device, is claimed, where a ring-shaped laser beam (6) is produced by the laser beam processing device for processing a component in a processing area and an optical element (16) is arranged in an optical path of the laser beam and deflects the laser beam to a sensor (24). The optical element is arranged in the processing area that comprises a reflection surface (20), which deflects the ring-shaped laser beam to the sensor. The sensor is a sensor or a device for detecting the performance or a power density distribution of the ring-shaped laser beam. The reflection surface is formed in cone-like manner, where the optical element has a longitudinal axis (18) that is aligned perpendicular to the radiation level of the ring-shaped laser beam. The optical element comprises a glass body formed in cylindrical manner or a reflection element. The reflection surface is formed as a thin layer or as coating on an interface of the glass body or the reflection element. The glass body in its inlet area for the ring-shaped laser beam has an inlet surface formed in curved manner. The reflection surface of the glass body is formed in curved manner. The optical element is directly connected with a connecting element with the sensor. The glass body is formed a hollow body. The reflection surface is formed on a reflection element, where the reflection surface is arranged to a wall spaced from the glass body by which the ring-shaped laser beam is guided on the reflection surface. |
