Patent ID: 8023120

Claim:
An ophthalmic surgical microscope defining a viewing beam path and comprising: a microscope main objective defining a focal plane of said ophthalmic surgical microscope and being mounted so as to permit said viewing beam path to pass therethrough permitting examination of a region of an object; an OCT-system for recording images of said object region; said OCT-system defining an OCT-scanning plane and providing an OCT-scanning beam and including a scanning mirror device for scanning said OCT-scanning beam; an optical unit mounted between said scanning mirror device and said microscope main objective for bundling the OCT-scanning beam exiting from said scanning mirror device and guiding the bundled OCT-scanning beam into a beam path passing through said microscope main objective to said object region; and, said optical unit including a movable lens assembly for shifting said OCT-scanning plane relative to said focal plane so as to provide an offset therebetween wherein an intensity distribution of the OCT-scanning beam has a smallest constriction.
