Abstract

An optical module for a machine for machining workpieces and/or for producing molded bodies by way of location-selective solidification of material powder into contiguous regions by a laser beam includes a housing for releasably fastening the optical module to the machine and a collimation optics changer releasably arranged in the housing, having at least two collimation optics which can be moved into a beam path of the laser beam for collimating the laser beam. The collimation optics changer has a mechanism for automatically changing the collimation optics.
