Abstract:
1. A microscope illumination system for switching between a first and a second microscope illumination mode, the microscope illumination system having a microscope illumination unit which, in order to provide the first microscope illumination mode, includes: an illumination source device for generating an illumination beam that propagates parallel to an optical axis, a scanning mirror device for deflecting the illumination beam in a plane perpendicular to the optical axis, a scanning eyepiece and a downstream scanning tube lens for imaging the scanning mirror device into a back focal plane of a microscope objective and for expanding the illumination beam, the microscope objective focusing the illumination beam onto a specimen to be examined, wherein, in order to provide the second microscopy illumination mode, the microscope illumination unit has a focusing lens which can be inserted into a path of the illumination beam in such a way that the illumination beam is focused into the back focal plane of the microscope objective, and the focusing lens is movable along the optical axis.
