Abstract

An operating microscope () for observing an eye () is provided. The operating microscope () comprises a main objective () and a fundus imaging system () that is positionable in the beam path () between the eye () and the main objective (), said fundus imaging system having an ophthalmoscopy magnifier (). The main objective () of the operating microscope () has a focal length in the range between 90 mm and 160 mm. The fundus imaging system () also can comprise an optics group (), the dispersion properties of which are matched to the dispersion properties of the ophthalmoscopy magnifier () in such a way that the optics group () compensates a chromatic aberration of the ophthalmoscopy magnifier ().
