Abstract

A camera system (1) has an imaging optical unit (2) for imaging an object field (3) into an image field (5). The imaging optical unit (2) has at least one variation optics module (19) having at least two refractive optical variation components (20, 21). The latter are configured such that they can be offset with respect to one another for the purposes of a targeted change of imaging properties. The variation components (20, 21) simultaneously guide an illumination beam path (13) for illuminating the object field (3) and an imaging beam path (14). Entry surfaces (25) and exit surfaces (26) of the variation components (20, 21) are oriented in the beam path (13, 14) such that illumination light (8) reflected at these optical surfaces (25, 26) is not reflected into the imaging beam path (14). At least one of the optical surfaces (25, 26) is configured as a freeform surface. The result is a camera system, the imaging optical unit of which allows targeted changing of imaging properties and is also free from undesired incident-light reflections.
