Microscopy system for observing fluorescence in ophthalmology

摘要

An ophthalmology microscopy system for observing fluorescence comprises an imaging system and an illumination system. The imaging system provides at least one optical imaging path producing a magnified multi-dimensional image of an object disposable in a focal plane of the imaging system, and comprises at least one optical observation filter. The illumination system provides an illumination beam path intersecting the focal plane of the imaging system at a variable angle of less than 90°. The microscopy system comprises first and second operating states. In the first operating state, radiation passing through the illumination beam path has at least in a section along the illumination beam path a spectrum free of a pass band of the observation filter. In the second operating state, radiation passing through the illumination beam path has a spectrum having a bandwidth of at least 200 nm in a range from 380 nm to 780 nm.

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.
