1. A device for calibrating a laser device which is designed to freely position a working laser beam in a predetermined working range, comprising
a sensor plate with several sensor fields for arrangement in a working area,
a perforated plate gauge with a plurality of calibration openings, wherein the plurality of calibration openings are each arranged in the region of one of the sensor fields, the surface of the calibration openings being smaller than the respective surface of a corresponding sensor field of the sensor plate
a control device for determining the relative position of the sensor fields to each other after exposing them through the calibration openings of the perforated plate gauge,
a pilot laser device for providing a pilot laser beam along the path of the working laser beam in order to calibrate a laser device by scanning the pilot laser beam by means of the sensor fields.
