Abstract

A microscope () is described, having an autofocus system () for executing a focusing procedure, having a first image sensor (), arranged in a first outcoupled beam path (), for acquiring a first image (); and a second image sensor (), arranged in a second outcoupled beam path (), for acquiring a second image (). The autofocus system () is embodied to ascertain a contrast difference based on contrast values of the first image () acquired by the first image sensor () and of the second image () acquired by the second image sensor (), and to set a relative location of the focal plane () with respect to the object plane () based on the ascertained contrast difference, the first and the second image () each encompassing image information furnished by the first and the second image sensor () each embodied as an area sensor.
