| 20090168166 | Stereoscopic Optical System And Method For Production Of A Stereoscopic Optical System - The invention relates to a stereoscopic optical system ( | 07-02-2009 |
| 20110063736 | IMAGING OPTICS WITH ADJUSTABLE OPTICAL POWER AND METHOD OF ADJUSTING AN OPTICAL POWER OF AN OPTICS - 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. | 03-17-2011 |

| 20100238541 | STEREO-EXAMINATION SYSTEMS WITH IMAGE ROTATION - A stereo-examination system including an objective arrangement configured to receive an object-side beam bundle emanating from the object plane and to convert the object-side beam bundle into an image-side beam bundle and a selection arrangement configured to select at least one pair of partial beam bundles from the image side beam bundle. The system also includes an image transmission apparatus configured to generate stereoscopic images of an object positionable in the object plane from the at least one pair of partial beam bundles and an illumination arrangement. The illumination arrangement includes a light source, a beam coupler to superpose a beam cross-section of the illumination beam with the image-side beam bundle, and a field of a plurality of state-changing elements. The elements are selectively switchable between a first state directed and a second state in which light of the illumination beam is and is not directed to the object plane. | 09-23-2010 |

| 20080204660 | Ophthalmoscopic attachment module and surgical microscope having an ophtalmoscopic attachment module - An opthalmoscopic attachment module ( | 08-28-2008 |
| 20080218695 | Optical device, use of an optical device according to the invention as well as method for blocking light reflections in the observation beam path of an optical device - The invention relates to an optical device for the examination of an eye, with at least one objective disposed facing the eye, at least one lighting source for illuminating the eye, an optical element and/or an optical arrangement disposed between the objective and the eye being examined, which optical element or arrangement produces an intermediate image of the plane examined within the eye, which is observed with the objective, whereby in the observation beam path of the optical device, at least one locally resolved attenuating element is disposed, which can be switched in a locally resolved manner into at least two transparency states. In addition, the invention relates to a method for blocking light reflections in the observation beam path of an optical device as well as the use of such an optical device for examining an eye. | 09-11-2008 |
