Abstract (en)
[origin: WO2018019625A1] The invention relates to a device for deflecting laser radiation (1), in particular for an SLS method or an SLM method, comprising a first lens array (2) having a plurality of lenses (3) arranged adjacent to each other, a second lens array (8) having a plurality of lenses (9) arranged adjacent to each other, a movable, in particular rotatable or pivotable, first mirror (5), which is arranged between the two lens arrays (2, 8) and deflects the laser radiation (1) that has passed through the first lens array (2) toward the second lens array (8) during operation of the device, and an objective (13), which focuses the laser radiation (10) that has passed through the second lens array (8) into a working plane (14) during operation of the device.
