Abstract: The modular laser individualization device (1) comprises a control unit, a laser beam generating unit (5) for generating laser radiation (20), a controllable beam guiding unit for directing the laser radiation on a document (23) controlled by the control unit to store a laser interaction individualization information in the document, and an attenuation unit. The laser beam generating unit is arranged in a beam generating module housing. The beam guiding unit is arranged in a functional module housing (2) formed from the beam generating module housing. The modular laser individualization device (1) comprises a control unit, a laser beam generating unit (5) for generating laser radiation (20), a controllable beam guiding unit for directing the laser radiation on a document (23) controlled by the control unit to store a laser interaction individualization information in the document, and an attenuation unit. The laser beam generating unit is arranged in a beam generating module housing. The beam guiding unit is arranged in a functional module housing (2) formed from the beam generating module housing. The functional module housing and the beam generating module housing are connected or connectable to each other by a radiation technology. The detachable connection is formed or formable via a first coupling element and a second coupling element, where the elements are releasably connectable or connected to each other. The first and second coupling elements comprise a guide unit, by which a reproducible relative positioning results in the connected state. Each of the first and second coupling elements has a circular passage opening, through which the laser radiation of the coupling elements is guided in the connected state. Each of the first and second coupling elements comprises centering elements, through which the passage openings of the coupling elements are centered to each other in the connected state. The beam generating module housing and the functional module housing are connected together by a light guide. The light guide is locked or lockable in the first coupling element so that the light guide or a light path of the laser radiation emitted from the light guide is guided or feasible centrally through the passage opening. The first coupling element is formed as a feeding flange, in which the light guide is locked or lockable, and the second coupling element is formed as a receiving flange, which is arranged in the functional module housing or in the beam generating module housing. The feeding flange and the receiving flange comprise asymmetrically designed attachment and/or guide elements so that the feeding and receiving flanges are detachably connectable with each other in only one orientation. A rotary table is disposed in the functional module housing and includes a document recording, which is movably arranged so that the recording is movable into a receiving position. A suction device is formed in or on the functional module housing and comprises a suction channel, in which an axis revolving diagonally to the throughflow direction of the suction channel is stored in a quiescent state, in which no fluid flow prevails in the suction channel, where a flap protruding into the flow path of the suction channel is arranged. A sensor is arranged in or on the pivoting range of the flap, by which a deflection of the flap at a fluid flow during the suction of fluid is detected. The attenuation unit is movable into the beam path or guides the beam path for attenuating the laser radiation so that the plane-parallel surfaces exhibit an orientation of 45[deg] relative to the laser radiation, and comprises plane-parallel surfaces having identical characteristics and having a body oriented with respect to each other at 90[deg] of the surfaces, where one of the surfaces is partially silvered formed. An independent claim is included for a laser individualization system comprising a laser individualization device.
