Patent ID: 8547633

Claim:
An operating microscope comprising: a binocular main microscope ( 11 ) with a main objective ( 1 ) having an optical axis, an objective plane that is perpendicular to the optical axis and a binocular main observer beam path intersecting the main objective at two main observation pupils ( 3 a , 3 b ) in the objective plane, the main observation pupils having centers interconnected by a first straight line ( 7 ) in the objective plane, a binocular co-observer microscope ( 13 ) with a binocular co-observer beam path intersecting the main objective at two co-observation pupils ( 5 a , 5 b ) in the objective plane, the co-observation pupils having centers interconnected by a second straight line ( 9 ) in the objective plane, the second straight line ( 9 ) having a center ( 6 ) point between the co-observation pupils, the first straight line ( 7 ) and the second straight line ( 9 ) intersecting at an angle, and a displacement arrangement that allows a displacement of at least a part of the co-observation microscope ( 13 ) so that the co-observer beam path displaces with respect to the main observer beam path such that the angle between the second straight line ( 9 ) and the first straight line ( 7 ) changes during the displacement, and so that the center point ( 6 ) between the co-observation pupils ( 5 a , 5 b ) in the objective plane displaces when there is a change in the angle between the second straight line ( 9 ) and the first straight line ( 7 ).
