Abstract

A microscope objective has axially adjustable correction mounts for adapting to different parameters influencing the imaging quality. The axial adjustment of the correction mounts relative to a stationary barrel is realized by an adjusting ring arranged on the outer side of the barrel by means of a bolt or screw which is arranged in the respective correction mount, is directed radial to the optical axis of the objective and engages in through-openings of threaded rings. The objective has at least three correction mounts which are adjustable in direction of the optical axis of the objective by at least one adjusting ring without additional rotation around the optical axis of the objective.
