Patent number: 9001419Abstract: 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.Type: GrantFiled: February 4, 2011Date of Patent: April 7, 2015Assignee: Carl Zeiss Microscopy GmbHInventors: Ingo Fahlbusch, Werner Kleinschmidt, Heinrich Bunger, Peter Schnüll, Wolfgang Hartje, Georg Herbst

Patent number: 8988797Abstract: 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.Type: GrantFiled: January 13, 2012Date of Patent: March 24, 2015Assignee: Carl Zeiss Microscopy GmbHInventors: Ingo Fahlbusch, Georg Herbst

Patent number: 8988780Abstract: The invention relates to a planapochromatically-corrected immersion microscope objective for high-resolution microscopy applications with changing dispersive immersion conditions, having a plurality of lenses and/or subsystems (T1, T2, T3) comprising lens groups and a corrective function (LA2) for eliminating spherical aberrations. According to the invention, the microscope objective has an additional corrective function (LA1) for eliminating longitudinal chromatic aberrations caused by dispersive changes in the immersion by changing the air gaps between the lenses or gap combinations, wherein the influence on the longitudinal chromatic aberration corresponds to a rotation of the curve s(?), which describes the color point (s) as a function of the wavelength (?).Type: GrantFiled: October 19, 2012Date of Patent: March 24, 2015Assignee: Carl Zeiss Microscopy GmbHInventors: Manfred Matthae, Georg Herbst
