Patent number: 8547633Abstract: An operating microscope has a main objective (1) that extends along an objective plane and is penetrated by a binocular main observer beam path and a binocular co-observer beam path. The binocular main observer beam path has two main observation pupils (3a, 3b) in the objective plane with centers on a first straight line (7). The binocular co-observer beam path has two co-observation pupils (5a, 5b) in the objective plane with centers on a second straight line (9). The first and second straight lines (7, 9) intersect. The co-observer beam path can be displaced with respect to the main observer beam path so that the angle between the second and first straight line (9, 7) changes. The center point (6) between the co-observation pupils (5a, 5b) in the objective plane displaces when there is a change in the angle between the second and first imagined straight lines (9, 7).Type: GrantFiled: August 5, 2010Date of Patent: October 1, 2013Assignee: Carl Zeiss Surgical GmbHInventors: Alfons Abele, Rupert Demleitner, Daniel Kolster

Patent number: 7697199Abstract: A lighting device (40) is described for an observation device (10), in particular for an ophthalmologic operating microscope, as well as such an observation device (10). The lighting device (40) has a light source (41) as well as a number of optical components, which are provided between light source (41) and an objective element (11). The optical components are designed according to the invention in such a way that the imaging of the lighting pupil (43) and the observation pupils is produced on the fundus of the eye (30). In this way, an exactly defined interaction of the lighting beam path (56) with an observation beam path is made possible, whereby practical requirements can be fulfilled relative to the homogeneity of the red reflex with simultaneous sufficiently good contrasting.Type: GrantFiled: October 14, 2004Date of Patent: April 13, 2010Assignee: Carl Zeiss AGInventors: Peter Reimer, Fritz Straehle, Daniel Kolster

Publication number: 20090224126Abstract: Among other things, a retaining device (10) for tilting and swiveling an apparatus, in particular a microscope, which is fastened to retaining device (10), is described, which has a fastening means (11) for fastening the apparatus, a tilting axis (12) for tilting the fastening means (11), and a swiveling axis (13) for swiveling the fastening means (11). In order to reduce the necessary structural space and to be able to guide cables through the axes, it is provided that the tilting axis (12) and the swiveling axis (13) lie in one plane and are aligned with one another in such a way that they intersect. Tilting and swiveling can be realized with the help of a specially configured gear (14). Retaining device (10) advantageously has two drives (15: 18) that can be actuated independently of one another. The drive direction of drives (15; 18) alone decides whether the movement is a tilting movement, a swiveling movement or a combined tilting/swiveling movement.Type: ApplicationFiled: February 18, 2009Publication date: September 10, 2009Inventor: Daniel Kolster

Publication number: 20090087252Abstract: First, a device (10) for limiting the angle of rotation of an object that is mounted in a rotatable manner is described, having a base element (12) that is mounted in a rotatable manner around an axis of rotation (11) for the uptake of an object to be rotated, and having a mechanism (13) for limiting the angle of rotation. Therefore, so that the rotation of base element (12) can be limited, for example, to a full 360 degrees, it is provided according to the invention that the mechanism (13) for limiting the angle of rotation has a pivoting stop (15) that is mounted in a rotatable manner around a pivoting axis (14), this stop being disposed on base element (12), that the mechanism (13) for limiting the angle of rotation has at least one, preferably two or more stops (16, 17) for limiting the pivoting movement of the pivoting stop (15) and that the mechanism (13) for limiting the angle of rotation has at least one counter-stop (18), which cooperates with pivoting stop (15).Type: ApplicationFiled: September 15, 2008Publication date: April 2, 2009Inventor: Daniel Kolster

Patent number: 7159831Abstract: An adjusting device (3) is suitable especially for use on a stand (1) for a surgical microscope (2). The adjusting device (3) makes it possible to move the surgical microscope (2) in a plane (9) perpendicular to the optical axis (8) of the surgical microscope (2). For this purpose, a transmission is provided in the adjusting device (3) which includes a coupling plate which is operatively connected to two force-transmitting elements. When this transmission is moved, at least one of the force-transmitting elements rolls off on the coupling plate. Alternatively, this transmission can be built up as a four-point linkage chain or contain a rhombic mechanism or lever mechanism. It is also possible to configure the transmission with belt elements or to configure the same as an eccentric arrangement having two offset rotation centers.Type: GrantFiled: February 23, 2004Date of Patent: January 9, 2007Assignee: Carl-Zeiss-StiftungInventors: Hartmut Gärtner, Gerhard Gaida, Franz Krug, Daniel Kolster, Alexander Enns
