Document Type and Number:
WIPO Patent Application WO2006067387

Abstract:
An improved laser machining apparatus is described in which the laser machining head (4) containing the laser focussing lens (24) is provided with protective covers (34, 40) on either side of the lens (24) to exclude foreign particles from the surfaces of the lens. In addition re-orientation of the laser column (2), which carries the laser beam (12) from a laser generator (3) to the machining head (4) is suggested as further protection for the lens (24).
