Abstract
A method for calibrating at least one optical sensor of a laser machining head is provided. The laser machining head comprises a first optical sensor, a deflection device, and a focusing device. A laser beam path of the first optical sensor passes through the deflection device and the focusing device. The method comprises the steps of: deflecting the beam path of the first optical sensor by the deflection device to a first position on a first reference; generating a first optical measurement signal based on measurement light received by the first optical sensor from the first position on the first reference; and determining a correction value for calibrating the first optical sensor based on the first optical measurement signal and according to a deviation of the first position on the first reference from a first target position, which is specified relative to a position of the machining laser beam.
