A system for individualizing an object to be marked by means of a laser, comprising a reference object, particularly a reference card having a base body and a reference marking having conversion material, the reference marking representing a coordinate system of the reference object and being selected from a group comprising: pattern, barcode, QR code, one or more polygons, a plurality of lines disposed at angles to each other, a plurality of dots, a width of the reference marking corresponding to one image point; and a device for individualizing an object to be marked by means of a laser, having a laser source for generating a laser beam, a two-coordinate deflection device for specifically deflecting the laser beam by varying spatial angles, a control device for controlling the laser source and the two-coordinate deflection device, and a table having a specified marking plane for receiving an object to be marked by means of the laser beam, wherein the control device is set up for controlling the laser source such that at least one laser beam can be generated at a first scanning intensity and a second marking intensity, wherein the scanning intensity is less than the marking intensity and no marking of the reference object takes place when irradiating the reference object at the scanning intensity, wherein the device comprises a light-sensitive detector implemented for capturing luminescent radiation emitted by the reference object, and wherein the light-sensitive detector is connected to the control device in order to associate a controlled direction of the laser beam with a detection of said luminescent radiation. a reference object, particularly a reference card having a base body and a reference marking having conversion material, the reference marking representing a coordinate system of the reference object and being selected from a group comprising: pattern, barcode, QR code, one or more polygons, a plurality of lines disposed at angles to each other, a plurality of dots, a width of the reference marking corresponding to one image point; and a device for individualizing an object to be marked by means of a laser, having a laser source for generating a laser beam, a two-coordinate deflection device for specifically deflecting the laser beam by varying spatial angles, a control device for controlling the laser source and the two-coordinate deflection device, and a table having a specified marking plane for receiving an object to be marked by means of the laser beam, wherein the control device is set up for controlling the laser source such that at least one laser beam can be generated at a first scanning intensity and a second marking intensity, wherein the scanning intensity is less than the marking intensity and no marking of the reference object takes place when irradiating the reference object at the scanning intensity, wherein the device comprises a light-sensitive detector implemented for capturing luminescent radiation emitted by the reference object, and wherein the light-sensitive detector is connected to the control device in order to associate a controlled direction of the laser beam with a detection of said luminescent radiation.
