Abstract: The invention relates to an illuminating device for a microscope with an illumination magazine comprising a plurality of light emitting units. A mechanical illuminator changer can change the light emitting unit currently active in the operative position. A filter magazine having a plurality of filter units is present, wherein a mechanical filter changer for changing the filter unit currently in the active operative position is associated with the filter magazine. At least one mechanical coupling component is provided for cooperation with the filter changer and the illuminator and for uniquely assigning each filter unit to a specific light emitting unit.

Abstract: The invention is directed to a multispectral illumination device for a microscope or for a reader. According to the invention, the illumination device comprises at least three receptacle positions for lighting modules and at least one receptacle position for coupling modules, the mechanical devices for connecting the lighting modules or coupling modules at the receptacle positions to the illumination device being designed in such a way that the lighting modules or coupling modules can be easily changed. Further, the receptacle positions are arranged in such a way that, with suitable selection of the lighting modules and coupling modules, all individual spectra of the lighting modules in a total spectrum are available simultaneously at the output of the illumination device.

Abstract: A stage drive for moving a microscope stage designed as a mechanical stage including a first drive element linked to a first output element, and a second drive element, which is linked to a second output element. Through first and second transmission elements, the first output element is linked to a first stage element and the second output element is linked to a second stage element of the mechanical stage supported by the first stage element. The stage elements are supported so as to be displaceable relative to a fixed base element in orthogonal directions X, Y in a plane extending normal to the optical axis of the microscope beam path. The at least one stage drive includes at least one drive element and at least one output element and is arranged in the base element so as to be displaceable in X direction and/or Y direction within an adjustment range and lockable.

Abstract: A changing device for receiving optical elements, particularly for microscopes, has a stand comprising a side wall, front wall and rear wall. This changing device is arranged at a holder in the telecentric part of the microscope beam path and is outfitted with a quantity of optical components influencing the beam path. The arrangement is mounted so as to be rotatable around an axis of rotation which is situated in the holder and which intersects the optical axis of the microscope beam path.

Abstract: A changing device for receiving optical elements, particularly for microscopes, has a stand comprising a side wall, front wall and rear wall. This changing device is arranged at a holder in the telecentric part of the microscope beam path and is outfitted with a quantity of optical components influencing the beam path. The arrangement is mounted so as to be rotatable around an axis of rotation which is situated in the holder and which intersects the optical axis of the microscope beam path. This axis of rotation defines, with the optical axis, a plane extending substantially perpendicular to the front wall of the microscope stand. The part of the changing device which is not located in the microscope beam path and which lies diametrically opposite to the part of the changing device that is located in the beam path is arranged so as to be directed toward the microscope stand and is adjacent to the front wall of the microscope stand.
