Abstract
In a microscope with an objective, a variable magnification system and an autofocus arrangement, the autofocus arrangement produces a projection beam path for the projection of an autofocus marking onto an observation object, and an imaging beam path which passes through an objective, for imaging on a detector the autofocus marking projected onto the observation object. The projection beam path and/or the imaging beam path then passes through the variable magnification system outside its optical axis.
