Abstract
The present invention concerns a system for the calibration of at least one parameter of a laser engraver, the laser engraver comprising on one hand an engraving system with a focusing lens positioned at a distance of the surface of an substrate intended to be engraved and on the other hand a vision system for at least the positioning and the verification of the engraving, the vision system including a camera associated with an appropriate illumination and, wherein the engraving device of the laser is arranged in such way that the engraving device works to engrave a substrate with specific engraved layout corresponding to variation of at least one parameter and wherein the vision system is connected to a comparison device of at least one measured engraved parameter with the template value of at least one stored data in a memorization device connected to a engraving correction device.
