摘要

The device comprises focusing lenses having symmetrical axis (5) for focusing laser beams (1) in a common focusing plain with adjustable intervals between the focusing points of the laser beam. The intervals are adjustable through a deflection angle of respective laser beam on a movable reflectors (8) associated to the laser beams. The interval and the angle of each reflector are adjustable against the symmetrical axis in such a way that the beam axes of the laser beam are deflectable with different deflecting angles determined through the respective angle of the reflectors. The device comprises focusing lenses having symmetrical axis (5) for focusing laser beams (1) in a common focusing plain with adjustable intervals between the focusing points of the laser beam. The intervals are adjustable through a deflection angle of respective laser beam on a movable reflectors (8) associated to the laser beams. The interval and the angle of each reflectors are adjustable against the symmetrical axis in such a way that the beam axes of the laser beam are deflectable with different deflecting angles determined through the respective angle of the reflectors in a central area of an aperture opening (7) of the focusing lenses. The focusing lens is formed as a F-theta-objective. The reflector has a plane mirror. The reflectors are linearly producible and pivotable to an axis and are movable along a curved web. The curved web has an arc-shaped area having a radius, which is twice as large like the interval of the central area of the aperture opening of the focusing optic against the respective reflectors movable along the arc-shaped area. The reflectors are movably arranged by a sled (15) and/or vehicle along a rail. The reflector is fixed relative to the respective sled and/or rail, where each reflector is associated to a drive. The reflectors associated to the laser beams are movably arranged along a common web. The reflectors are movable respectively in pairs on both sides of the symmetrical axis in an asymmetrical position. The individual laser beams are deflectable additionally to the movable reflectors to immovable reflectors. The device has a further laser beam along the symmetrical axis in the aperture opening of the focusing optic with an unchangeable angle of the laser beam.
