  • Patent number: 8804236
    Abstract: A microscope system for imaging of an object that can be placed in an object plane of a microscope system includes an imaging system for providing at least one pair of optical imaging paths that include a stereoscopic angle in the object plane. The imaging system includes a first subsystem comprising a first plurality of optical lenses that are commonly traversed by both optical imaging paths of the at least one pair of optical imaging paths. The imaging system also includes a second subsystem comprising a second plurality of optical lenses that are traversed by only one optical imaging path. At least two optical lenses of the first plurality of optical lenses and at least two optical lenses of the second plurality of optical lenses are displaceable relative to one another along a common optical imaging path to respectively vary a magnification of the representation of the object.

  • Patent number: 8284482
    Abstract: A microscope or stereomicroscope for representing an object that can be placed on an object plane of the stereomicroscope provides at least one pair of optical paths and comprises at least one deflection element with a reflecting surface and a representation system containing several optical elements. The optical elements include a plurality of lenses. In addition, the optical elements are configured in such a way that pupil planes of the optical representation paths intersect the reflecting surface of the deflection element or are located at a distance from said reflecting surface less than 1.5 times the diameter of one of the reflecting surfaces along the optical representation paths on the closest lens of the plurality of lenses. An alternative embodiment provides a stereomicroscope with a particularly compact construction, in which at least one pair of optical representation paths is reflected on a first, second, third, and fourth reflecting surface.

  • Patent number: 8194328
    Abstract: The invention relates to optics comprising adjustable optical elements and, if desired, lenses of fixed focal lens. By use of an appropriate controller for the adjustable optical elements, characteristics of the optics can be advantageously varied. For this purpose, systems are provided which are suitable for use as surgical stereo-microscope, objective, ocular or zoom. A zoomable imaging optics comprises lenses and of variable optical power, which are oppositely controlled by means of a controller to change an imaging ratio, so that the optical power of the one lens is increased and the optical power of the other lens is decreased. Moreover, the imaging optics may comprise still further assemblies of fixed optical power.
