Abstract
A laser processing head comprising a focusing device for focusing a processing laser beam onto a workpiece, the focusing device arranged in a processing beam path, an optical imaging device comprising a detector, wherein the optical imaging device is configured to image observation radiation from a processing region of the workpiece onto the detector along an observation beam path passing through the focusing device, a beam splitter for separating the observation beam path from the processing beam path of the processing laser beam, imaging optics arranged in the observation beam path between the beam splitter and the detector; and a stop arranged between the imaging optics and the detector, wherein the imaging optics produces an image of the stop in the processing beam path of the processing laser beam between the beam splitter and the workpiece.
