Abstract: To improve the use properties of a visualization and/or illumination system (1), with which an object can be illuminated with non-visible illumination light (2) during a medical intervention, some of the illumination light (2) transported by the system (1) is branched off and guided to a converter (3), which picks up, in particular detects or absorbs, the illumination light (2) and subsequently converts it into an indication signal (4) that is perceivable by humans and outputs this indication signal (4). Using the indication signal (4), a user can thus quickly and easily check whether or not the illumination light (2) is currently being emitted by the system (1).

Abstract: An optical assembly (1, 100) is provided, including an optical functional unit (2), a housing (3), which at least partly encloses the optical functional unit (2), and an adjusting device (4), by which a desired position of the optical functional unit (2) relative to an optical axis (16) of the optical assembly (1, 100) is settable. The adjusting device (4) is configured to the effect that the position of the optical functional unit (2) is set by way of an operative connection (5) between an actuation part (9, 10) and a holding part (11, 12, 28, 29) of the adjusting device (4). The operative connection (5) is configured in the region of a closed housing wall (6), and wherein the optical functional unit (2), after the setting of the desired position, is fixable in this position.
