MODULE OPTIQUE MUNI D'UN DISPOSITIF PERMETTANT DE CHANGER AUTOMATIQUEMENT UNE OPTIQUE DE COLLIMATION

摘要

The invention relates to an optical module (2) for a machine (1) for machining workpieces and/or for producing molded bodies by way of location-selective solidification of material powder into contiguous regions by means of a laser beam. The optical module (2) comprises a housing (8) having means for releasably fastening the optical module (2) to the machine (1), and a collimation optics changer (3) releasably arranged in the housing (8), having at least two collimation optics (4), which can be moved into a beam path of the laser beam for collimating the laser beam. According to the invention, the collimation optics changer (3) has a mechanism for automatically changing the collimation optics (4).
