Patent ID: 7554723

Claim:
An ophthalmic surgical microscope for microsurgery for viewing an object or an intermediate image generated by the object, the ophthalmic surgical microscope defining a viewing beam path and comprising: an objective arrangement defining a focal intercept and being focusable to vary said focal intercept so as to intersect at an intercept point on an object plane or at an intermediate image thereof; an autofocusing system having a component assembly for detecting a focusing state of said objective arrangement and for outputting a focusing actuating signal for said objective arrangement; a focus offset adjusting unit assigned to said autofocusing system for outputting a focus offset signal to adjust said objective arrangement by a predetermined focus offset starting from a first focusing state wherein said objective arrangement is focused on a first object plane to a second focusing state wherein said objective arrangement is focused onto a second object plane; an ophthalmoscopic magnifier; and, means for selectively moving said ophthalmoscopic magnifier between a first position whereat said ophthalmoscopic magnifier is disposed in said viewing beam path and a second position whereat said ophthalmoscopic magnifier is outside of said viewing beam path.
