Abstract
An apparatus for non-contacting modification of the surface of an article such as for labeling a glass article, characterized by a laser beam, a sweep device for deflecting the laser beam as a swept beam in a given path, a deflection device separate from the sweep device for deflecting the swept beam in a desired path for forming a label on the surface of the article. Due to the separation of the deflection device and sweep device, the sweep device can be constructed as small as possible with a low moment of inertia for the movable parts to enable obtaining significantly higher sweep frequencies. As a result, a high sweep frequency, preferably in amounts of at least 500 Hz, can be obtained and a sharp edge erosion without macroscopic splintering is guaranteed during the labeling of a glass article with the apparatus.
