Abstract
A surgical microscope includes an optical assembly to image an object plane with a microscope main objective system, through which a first stereoscopic partial beam path with a first optical axis and a second stereoscopic partial beam path with a second optical axis pass. An illumination device includes a light source assembly to provide illumination light in a luminous plane, with a radiant field stop, and an illumination optical unit which at least partially images a luminous object arranged in the luminous plane in the illumination beam path into a luminous image plane located in the microscope main objective system or for the vertical distance z of which from the microscope main objective system on the side facing the object region or the side facing away from the object region, in relation to a focal length f of the microscope main objective system, the following applies: z/f<10%.
