Abstract: Among other things, a variable diaphragm is described for a lighting device and/or for an observation device inside an optical observation apparatus for imaging an object and/or an intermediate image produced by an object, particularly for a stereoscopic observation apparatus, wherein the variable diaphragm is provided for at least one beam path of the lighting device and/or for a beam path of the observation device. According to the invention, the variable diaphragm can be controlled in order to produce a specific lighting geometry by regions. In addition, the variable diaphragm is formed for the utilization of all directions of polarization of the light of a light source. Further, a lighting device, an optical observation device, as well as an optical observation apparatus are also described.

Abstract: The present invention relates to a surgical microscopy system, comprising a surgical microscope, a stand comprising a base and a plurality of pivotally connected arms, the surgical microscope being mounted to one of the arms, wherein the pivotally connected arms are arranged to be movable with respect to each other such that the surgical microscope is movable relative to the base, and wherein a conventionally provided lead is replaced by one or more leads fulfilling the function of the single lead together. The present invention also relates to a surgical microscopy system, wherein data or/and energy is transmitted to the surgical microscope by wireless transmission.

Abstract: A stereo-examination system for imaging an object 8 is proposed, comprising an objective arrangement 3 having an optical axis 5 and an object plane 7 for positioning the object 8 to be imaged, wherein the objective arrangement 3 receives an object-side beam bundle 11 emanating from the object plane 7 into a solid angle region 9 and converts the same into an image-side beam bundle 13, a selection arrangement for selecting at least a pair of partial beam bundles 19, 20 from the image-side beam bundle 13, and an image transmission apparatus 51, 52 for generating a representation of images of the object 8 provided by the partial beam bundles 19, 20.

Abstract: A microscopy system and method provides functionalities for a user which are controllable by the user by displacing a body portion of the user. The functionalities comprise displacing a portion of a support mounting the microscopy optics and adjusting a stereo base for generating stereoscopic representations of an object.

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.

Abstract: A microscopy system for eye surgery with an objective lens is suggested, which provides a retroillumination system to generate a so-called red reflex illumination during an eye-surgical treatment, in particular during a cataract operation.

Abstract: An apparatus for treating body tissue includes a treatment instrument 1 for treating the body tissue and a measuring unit 3 for measuring the actual value of a parameter of the body tissue at at least one measuring point. An identifier 4 is connected to the measuring unit 3 for identifying the body tissue to be treated on the basis of the actual value and for outputting a coordinate signal containing the coordinates of the body tissue to be treated. A positioning device 2 receives the coordinate signal and moves the treatment instrument 1 to the body tissue to be treated. An updating device 8 is connected to the measuring unit 3 and the identifier 4 and outputs an updating signal for triggering renewed measurement of the actual value and renewed identification of body tissue to be treated.

Abstract: A microscopy system for imaging an object is proposed, comprising: microscopy optics including an objective system (3) with an object plane (13) whose working distance (A) from the objective system is adjustable, and a first projection system for projecting at least one shaped analysis light beam (33, 34) onto the object and for generating at least one light spot (39) on the same. The analysis light beam (33, 34) is shaped such that a shape of a cross-section of the analysis light beam (33, 34) changes in beam direction.
