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.

An immersion objective comprises an objective body in which optical components are accommodated, at least one immersion fluid tank and at least one objective-body coupling connection on the objective body. The immersion fluid tank can be supported in a detachable manner via the objective-body coupling connection. At least one pump is supported via the objective body, wherein the pump is arranged in order to convey immersion fluid from the immersion fluid tank to an objective front side. A control electronics component is supported via the objective body and is configured to control the at least one pump.

A protective device for protecting microscope components from contact with a liquid comprises at least one objective protection ring for arrangement around an objective, wherein the objective protection ring comprises an annular contact area for contacting the objective; and a stand protector with a drainage channel for draining a liquid. The objective protection ring comprises a lower ring area located below the contact area and protruding further outwards radially than the contact area in order to form a free space in the inward direction.

An objective-changer apparatus for a microscope system comprising an objective-transfer element with at least one objective holder for holding an objective that has been provided with an adapter, wherein the objective-transfer element moves a selected active objective into position in a transfer position in controlled fashion and an objective axis of the active objective does not coincide with the optical axis of the microscope system in the transfer position. A receiving apparatus is adjustable in the direction of the optical axis of the microscope system and can be brought into contact with the adapter. The receiving apparatus transports the active objective along a transport path in a transport direction orthogonal to the microscope system's optical axis between the transfer position and a work position in line with the microscope system's optical axis. The transport path is shorter than the extent of the objective holder in the transport direction.

A device for forming an immersion film between a front lens of a microscope objective and a preparation on an inverted microscope. The device includes a protection device for preventing fluid leakage from the immersion film region, and an apparatus for supplying the immersion fluid (auto-immersion) to the immersion film region. The protection device is arranged statically in the main part of the microscope stand and the means for supplying immersion fluid to the immersion film region is connected to the protection device by means of an Aquastop system.

A controller for microscope lenses for correcting spherical aberration and for adjusting particularly difficult to access microscope lenses to an optimum of imaging quality, enabling automatic adjustment of the different actuators of a microscope lens, to effect a simple, cost-effective, user-friendly, and precise balance, particularly of cover slip deviations and different base thicknesses of Petri dishes for the purposes of increasing imaging quality. At least two movable elements of a microscope objective supporting lenses or lens groups, are provided in a movable manner in the axial direction along the optical axis of the microscope objective relative to the housing of the microscope lens in a motor-actuated manner by way of respective adjusting rings. A controller externally controlled and disposed in the microscope lens is provided for storing different characteristic curves for paths of motion of the movable elements.

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.

Attachment of optical microscope components

The present disclosure relates to a family of microscopes, each with at least one lens group that includes at least one lens and a lens mount and moves along the optical axis via a drive system for The drive system includes a rotary motor and transmission elements to convert the rotary motion to linear motion to transmit the translational movement to the lens group, and, simultaneously, to prevent rotations of the lens group about the optical axis. In an embodiment, the rotating output shaft of the motor is connected with a screw spindle that engages with a threaded hole machined into the lens mount, so that the lens group is directly moved in a translational manner. The engagement of the screw spindle with the lens mount both effects the translational movement of the lens group and secures the lens group against rotation about the optical axis.

An objective lens assembly is provided, with a sleeve, a first positioning member arranged in the sleeve, which is housed displaceable in longitudinal direction of the sleeve and holds at least one lens, a first adjustment unit which brings the first positioning member into abutment on the inside of the sleeve such that the first positioning member rests against the inside of the sleeve in a first linear contact area and at the same time the displaceability of the first positioning member is maintained. More than one positioning member can be utilized along with multiple lenses and can utilize simple mechanical structures (e.g., blind- and through-holes and pins or shanks) and/or magnetic or magnetizable materials to maintain a desired position of the sleeve.

A microscope for observing an object selectably using the bright-field transmitted light contrast procedure or the incident-light fluorescence contrast procedure. During the bright-field transmitted light contrast procedure, an illumination beam path is directed from a bright-field light source to the object and an imaging beam path is directed from the object through the microscope objective into the microscope tube, which includes a fluorescence unit that includes a fluorescence excitation light source, an illumination optical system, a filter set having at least one excitation filter and at least one emission filter, as well as a beamsplitter. The fluorescence unit is mounted movably, so that in a first end position of movement the beamsplitter and the emission filter are out of the imaging beam path of the microscope and in a second end position of movement they are in the imaging beam path between the microscope objective and the microscope tube.
