The device has a mirror unit (6) i.e. micro mechanical component, including a mirror element (5) that is actuated by a semi-permeable optical probe (8) for a rearward-reflected beam (16). A receiving optical unit (17) includes a focusing unit (19) and a radiation dis-aligning unit (18), and an object beam with the dis-aligning unit is moved in a direction of an optical axis of the receiving optical unit. The object beam is emitted from the mirror element on a detection unit (7), where the mirror element lies on an outer side of the receiving optical unit.
