ADJUSTMENT FOR A BESSEL RAIL PROCESSING OPTICS AND PROCEDURES

摘要

A device (101) is revealed for an adjustment of a machining optics (3) of a laser machining machine (1), whereby the machining optics (3) are trained to form a laser beam (5) in the laser machining machine (1) and to focus along a drop beam axis (21) such that a machining laser beam (5A) a preset Bessel beam focus zone (7) can be formed in a workpiece to be processed (9). The device (101) includes an input area (104) for recording the processing laser beam (5A),a focus zone training area (106),intended to permit the formation of a measurement focus zone (107) by the captured processing laser beam (5A) along a target axis (110) and an imaging unit (111),which has a lens (113) and a detector surface (115A), with the lens (113) laser radiation (105),which, after formation of the measuring focus zone (107), leaves the focus zone training area (106) along an axis defined by the target axis (110) on the detector surface (115A).
