Abstract:
The invention relates to an Illumination and observation system ( 1 ), in particular for an ophthalmic microscope. The system comprises a first observation pupil ( 4 ) and a second observation pupil ( 5 ) for the eyes of an observer such as an assistant. Further, the system comprises a coaxial illumination ( 6 ) in the first observation pupil ( 4 ) and a main illumination ( 7 ), the coaxial illumination ( 6 ) being adapted to generate a red reflex ( 13 ) in the observed eye in operation and the main illumination having a larger field of illumination than the coaxial illumination ( 6, 10, 11 ). In order to facilitate usage of the system ( 1 ) and/or the microscope ( 2 ) and to create a superior stereoscopic view using the red reflex ( 13 ), a control subsystem ( 21, 27 ) is provided which is adapted to automatically adjust an intensity of the main illumination ( 7 ) depending on a change in an intensity of the coaxial illumination ( 6 ).

Claim (Index 2):
Illumination and observation system ( 1 ) according to  claim 1 , wherein the control subsystem ( 21 ,  27 ) is adapted to set a ratio of the intensity of the main illumination ( 7 ) to the intensity of the coaxial illumination ( 6 ) at a target ratio independent of a change in the intensity of the coaxial illumination ( 6 ).
