Patent number: 7394593Abstract: The invention relates to a transmitted-light base (1) for illuminating an object (15) for imaging through a zoom microscope (21), the transmitted-light base (1) comprising an integrated light source (3) having an associated electrical power regulation system (31) for generating a suitable radiation flux, and means (5, 6), capable of being added downstream, for generating a specified spectral intensity distribution. To allow compensation for brightness changes of low dynamic range, such as those occurring in particular during zooming, a continuously controllable mechanical brightness regulator (4) is proposed which is activatable by means of an associated adjustment device (41) in such a way that the illumination intensity of the transmitted-light base (1) is controllable with no change in the spectral intensity distribution.Type: GrantFiled: November 23, 2005Date of Patent: July 1, 2008Assignee: Leica Microsystems (Schweiz) AGInventors: Ruedi Rottermann, Patrick Kopf, Otto Geschwentner, Klaus-Peter Zimmer

Patent number: 6816321Abstract: The invention relates to an afocal zoom (1) for use in microscopes of high resolution and high zoom factors having a tube lens (11), the zoom comprising four successive optical assemblies (G1, G2, G3, G4) when viewed from the object end, the first assembly (G1) having a positive focal length (f1), the second assembly (G2) a negative focal length (f2), the third assembly (G3) a positive focal length (f3), and the fourth assembly (G4) a negative focal length (f4), and the first and the fourth assembly (G1, G4) being arranged in stationary fashion and the second and the third assembly (G2, G3) being arranged movably for modifying the magnification of the zoom (1), the zoom magnification decreasing with increasing distance (D23) between the two assemblies (G2, G3). The zoom operates in the range of “useful magnification” of the microscope with sufficient contrast if the zoom meets the meets specific conditions.Type: GrantFiled: May 8, 2003Date of Patent: November 9, 2004Assignee: Leica Microsystems (Schweiz) AGInventors: Klaus-Peter Zimmer, Ruedi Rottermann

Patent number: 6204963Abstract: The invention relates to a tubular intermediary unit for a microscope comprising a relatively small upper part and a similarly small lower part, the upper part being pivotable about an axis of rotation relative to the lower part. Two deflecting mirrors are located in the observation beam path in the upper and lower parts. At least one of the deflecting mirrors can be pivoted, preferably about the same axis of rotation about which the upper part pivots, depending upon the tilt angle of the upper part relative to the lower part. The invention allows an observer to freely adjust an eyepiece tube carried by the upper part without changing the view on the field of vision under the microscope.Type: GrantFiled: May 14, 1999Date of Patent: March 20, 2001Assignee: Leica Microsystems AGInventors: Paul Grafenhain, Ruedi Rottermann
