Beschreibung
Zusammenfassung:	The invention relates to a beam expander (100) comprising a receiving tube (105) with a light inlet opening (107) and a light outlet opening (109). The beam expander (100) additionally comprises at least one optical unit (112), which is movably arranged in a beam path between the light inlet opening (107) and the light outlet opening (109) of the receiving tube (105) in a movement direction (117), for changing the diameter of a beam bundle (110) coupled in via the light inlet opening (107). The beam expander (100) also comprises a guide unit (120), which is coupled to the optical unit (112), for guiding the optical unit (112) in the receiving tube (105) and a linear drive coupling unit (125), which is mechanically coupled to the guide unit (120), in order to couple and/or convert a movement or rotation of a drive element (127) into a movement of the guide unit (120).
