Abstract: An adapter that can connect to an objective has a receiving area for receiving the objective. The adapter has holding structures which extend essentially in a plane directed transversely to the objective axis of the objective and which are designed to engage corresponding structural elements of an adapter receptacle while the adapter is being inserted into the adapter receptacle, thereby preventing the adapter from already moving in the direction of the objective axis while the adapter is being inserted into the adapter receptacle. A device for holding an adapter, can include an adapter receptacle for receiving the adapter and an adapter and also for moving an optical element into the objective axis. An adjusting device can include the adapter and the adapter receptacle.

Abstract: The invention relates to an optical assembly that can be interposed into the observation beam path of a microscope, comprising a first mount. In the first mount, a stack of optical elements for a polarization optical, differential interference contrast method, is arranged to facilitate a first observation method. The stack comprises, inter alia, a polarizer, polarization-optical shearing elements, and an analyzer. The analyzer is arranged in the stack with regard to its polarization direction in a predetermined orientation relative to the polarization direction of the polarizer. The stack of optical elements in the first mount is arranged such as to be interchangeable. Further, the assembly comprises at least one additional mount for receiving optical elements for at least one additional observation method.

Abstract: An X-Y stage for microscopes including a base stage element, an intermediate stage element, and an upper stage element.

An intermediate stage drive with an output link is coupled to the intermediate stage and provides a second drive direction. The X-Y stage further includes at least one of a first mechanical switch for reversing the first displacement direction and a mechanical second mechanical switch for reversing the second displacement direction.

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: The invention relates to an inverted microscope, including a microscope stand having a stand housing. The stand housing has a rear wall, a front wall, and side walls, and an objective turret, a focusing drive, and a rotatable retaining device, which is designed as a reflector turret and which has a plurality of locations for receiving exchangeable optical components. The retaining device protrudes from a side wall of the stand housing so that the optical components can be quickly changed without having to remove the retaining device from the stand housing.
