Illumination and observation system for an ophthalmic microscope, an ophthalmic microscope including such a system, and microscopy

摘要

The present invention relates to an illumination and observation system (1), in particular for an ophthalmic microscope. The system includes a first observation pupil (4) and a second observation pupil (5) for an observer eye, such as an assistant. Furthermore, the system is adapted to form a red reflex (13) in the eye observed during the operation, coaxial illumination (6) in the first observation pupil (4) and coaxial illumination (6, 10). , 11) and a main illumination (7) having a larger illumination field. In order to facilitate the use of the system (1) and / or the microscope (2) and to form an excellent stereoscopic field using the red reflex (13), the intensity of the main illumination (7) is reduced. A control subsystem (21, 27) is provided that is adapted to automatically adjust in response to changes in the intensity of the coaxial illumination (6).
