Patent number: 7064911Abstract: The invention relates to a guide system for optical systems, particularly for zoom systems, with which optical assemblies such as lenses and/or sets of lenses can be moved along an optical axis (16). The proposed guide system comprises a housing (2) defining an internal diameter (1) and extending along the optical axis (16). A slide (3) is configured to accommodate an optical assembly (19) and has a sleeve segment (15) which has on its outside a plurality of contact surfaces (4) for abutment on the internal diameter (1) of the housing (2). For defined movement of the slide (3) along the optical axis (16) a drive unit (12) is provided. A device (17) serves to hold the sleeve segment (15) at the internal diameter (1), another device (18) serves to secure the slide (3) against rotation in the cross-sectional area of the housing. The guide system according to the invention provides guidance which is absolutely free from play and low in friction.Type: GrantFiled: August 20, 2004Date of Patent: June 20, 2006Assignee: Leica Microsystems (Schweiz) AGInventor: Peter Soppelsa

Patent number: 6760166Abstract: A zero-clearance, axially displaceable aligning mount system for optical components includes an unthreaded mount receptacle having a transverse orifice and includes an aligning mount carrying lens elements or lens combinations. A cured plastic casting compound forms a thread substitute in the region of the transverse orifice and beyond it. Coating of this region with an antiadhesion agent, prior to application of the casting compound in pasty form, prevents the molded threads from sticking.Type: GrantFiled: March 6, 2003Date of Patent: July 6, 2004Assignee: Leica Microsystems (Schweiz) AGInventors: Albert Ritz, Otto Geschwentner, Peter Soppelsa, Heinz Zimmermann

Patent number: 6563113Abstract: The invention relates to a novel type of microscope with an illuminating beam which is guided through the magnification power changer with optimized light intensity parallel to the observation beam. The invention specifically relates to a stereo fluorescence microscope comprising a set of quickly replaceable filters in interchangeable filter carriers. The novel design offers good light efficiency on the object. Malfunctions occurring as a result of intrinsic reflections or fluorescence phenomena inside the microscope are avoided.Type: GrantFiled: May 4, 2000Date of Patent: May 13, 2003Assignee: Leica Microsystems (Schweiz) AGInventors: Thomas Amann, Jurij Sterban, Ruedi Rottermann, Peter Soppelsa, Heinz Zimmermann

Patent number: 6487010Abstract: The invention describes a focusing drive for optical instruments that has, in addition to a pinion (1) and toothed rack arrangement (1, 2), slide rods (4) as guidance means for continuously changing the relative position of optical assemblies with respect to one another. The toothed rack (2) has a plurality of support elements (3) that are arranged—for example in angled fashion—on either side of its longitudinal extent. The support elements (3) are designed so that they have a shallow S-shape in cross section. In addition, they are dimensioned in such a way that they touch the contact surface of the one housing module (5) only with their planar end regions (3a). The result is a resilient or flexing motion upon actuation of the pinion (1), thus achieving smooth and zero-backlash adjustment.Type: GrantFiled: May 10, 2001Date of Patent: November 26, 2002Assignee: Leica Microsystems AGInventors: Peter Soppelsa, Vui Fah Loh
