Abstract:
The invention relates to an Illumination and observation system ( 1 ) for a microscope ( 2 ), in particular a microscope for performing eye surgery, a microscope and a microscopying method. The Illumination and observation system ( 1 ) comprises a first, second, third and fourth observation pupil ( 4, 5, 8, 9 ) for the eyes of two observers such as a surgeon and an assistant, a coaxial illumination ( 6, 10, 11 ) in the first, third and fourth observation pupil ( 4, 8, 9 ) to generate a red reflex ( 13 ) in the first, third and fourth observation pupil ( 4, 8, 9 ), and a main illumination ( 7 ) in the second observation pupil ( 5 ). In order to provide a wide illumination of the surroundings, the main illumination has a larger field of illumination than the coaxial illumination ( 6, 10, 11 ) in any of the first, third and fourth observation pupil ( 4, 8, 9 ). To provide superior observation quality, in particular for the observer using the second observation pupil ( 5 ) and further to be able to generate a visible and homogenous red reflex in the second observation pupil ( 5 ), it is provided according to the invention that the main illumination overlaps at least 50% with the second observation pupil ( 5 ) to generate a red reflex ( 13 ) in the second observation pupil ( 5 ). Further improvements relate to align the main illumination ( 7 ) within ±5° to an optical axis ( 12 ) of the second observation pupil ( 5 ) and to overlap the coaxial illumination ( 6, 10, 11 ) at least 50% with the respective first, third and fourth observation pupil ( 4, 8, 9 ).

Claim (Index 4):
Illumination and observation system ( 1 ) according to  claim 1 , wherein each of the first, second, third and fourth observation pupil ( 4 ,  5 ,  8 ,  9 ) is associated with a separate light source ( 16 ).
