Title

Vorrichtung zum Bearbeiten von Werkstuecken mit einem Laserstrahl

Other Title
Device for machining workpieces using a laser beam
Abstract
Device for the high-frequency repetitive deflection of a standing light beam, in particular a laser beam (10), comprising a rotating motorized mirror (11) which has at least one beam-deflecting mirror surface. In order to achieve the high-frequency deflection of the light or laser beam, the device is designed in such a way that the mirror (11) has a helical screw surface (12) acting as the beam-deflecting mirror surface and its axis of rotation (13) is the screw axis of rotation of the helical surface.
