  • Patent number: 6853494
    Abstract: The invention concerns a zoom system, having various materials (glass types) and variable air spaces, for example for a surgical (stereo)microscope, constructed from four symmetrically arranged lens groups (2 through 5), each two lens groups (2, 5; 3, 4) being arranged identically and in mirror-image fashion with respect to one another. As a result of the special selection of glass types having anomalous partial dispersion, and the specific design features, a high zoom factor is achieved with a short overall length, as well as good correction of the secondary spectrum, astigmatism, and field curvature.

  • Publication number: 20040252371
    Abstract: A stereomicroscope includes a binocular tube for a pair of main stereo beam paths and an assistant's tube for an assistant's beam path.

  • Publication number: 20040061932
    Abstract: An ophthalmic surgical microscope having an apparatus for illumination of a subject with illuminating light, in which the spectral selection and/or polarization and/or phase properties of the illuminating light are selected in such a way that the illuminating light is reflected, absorbed, and/or scattered differently in the different media of the patient's eye (5) and/or at the media interfaces. The light thus modified is coupled out of the observation beam path (2) of the stereomicroscope (1); the nature, shape, and position of the individual media and/or their interfaces are determined using an evaluation unit (14); and an electronically generated optical image is in turn coupled via a projector (16) or other display into the observation beam path (2).
