Abstract
A widefield microscope illumination system and method with a microscope objective and an illumination light source that sends widefield illumination light along illumination beam paths. Illumination light penetrates into the microscope objective through illumination light entry sites located within a predetermined annular or annular-segment-shaped illumination light entry area having a large offset to an optical objective axis of the objective. A spatially resolving light detector detects light sent from an illuminated sample through the microscope objective along a detected light beam path. An automatic illumination light beam path manipulation device is controlled by a control system, which is arranged in front of the microscope objective in relation to the direction of the illumination light beam path, and by means of which illumination light beam path manipulation device the illumination axes are automatically movable at time intervals to a plurality of different illumination light entry sites.
