Abstract: A device for attaching a first optical microscope component part to a second part includes an annular receptacle attached to the second part and an annual insertion part. The annular insertion part includes outside-conical retaining projections. The receptacle includes a base ring having a retaining collar with an inside cone tapering away from the base ring and in which a lateral opening is formed, through which the insertion part can be inserted in the receptacle such that it is located on a pre-locking position in which the annular openings overlap. The insertion part and the receptacle can be moved by reciprocal rotation from the pre-locking position into a locking position in which the outside-conical retaining projections of the insertion part are seated against the inside cone of the retaining collar and press the insertion part on the base ring, whereby the insertion part is locked to the receptacle.

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.
