Claim:
1. An ophthalmology microscopy system for observing fluorescence, comprising: an imaging system providing at least one optical imaging path producing a magnified multi-dimensional image of an object disposable in a focal plane of the imaging system, with the imaging system comprising at least on optical observation filter; and a first illumination system providing a first illumination beam path intersecting the focal plane of the imaging system at a variable angle of less than 90°, or less than 80°, or less than 75°; wherein the microscopy system comprises first and second operating states; wherein radiation passing through the first illumination beam path in the first operating state has at least in a section along the illumination beam path a spectrum being free of a pass band of the observation filter; and wherein radiation passing through the first illumination beam path in the second operating state has a spectrum with a bandwidth of at least 200 nm, or at least 250 nm, and being in a range from 380 nm to 780 nm, wherein the first illumination system comprises a handle piece comprising a rigid light guide, wherein the rigid light guide is configured for being disposed in at least one of a visceral cavity, hollow organ and vitreous body of an eye ball.
