Zusammenfassung:	The invention relates to an optical unit for use in a system for manufacturing a three-dimensional workpiece by a beam melting method. The optical unit includes: an optical system for generating a beam and guiding the beam to a predetermined site; and a receptacle having a receptacle base and an opening arranged in the receptacle base, the opening being permeable to the beam such that the beam can pass through the opening. The optical unit has a lower section comprising a receptacle base and having two side walls each extending parallel to a first direction, and an upper section connected to the lower section and having two side walls each extending parallel to the first direction, where the lower section and the upper section are arranged offset from each other, a first of the side walls of the lower section and a first of the side walls of the upper section do not extend in the same plane, and a second of the side walls of the lower section and a second of the side walls of the upper section do not extend i
