Patents by Inventor Thomas Pozivil

Thomas Pozivil has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Telescope and panfocal telescope comprising planoconvex of planoconcave lens and deflecting means connected thereto
    Patent number: 7672049
    Abstract: The invention relates to a telescope which is used to inject and/or to extract, by reflection, emitting and/or capturing bundles of beams. According to the invention, at least one deflecting means is joined to the planar surface by means of at least one lens of the telescope objective unit, which is embodied as a plan convex or plan concave lens. The lens is used as a lens of the objective unit and as a holder for the deflection means. The number of optical components in the telescope about one of the holders is reduced due to the dual function thereof.
    Type: Grant
    Filed: November 28, 2005
    Date of Patent: March 2, 2010
    Assignee: Leica Geosystems AG
    Inventors: Andreas Fruhmann, Thomas Pozivil, Jürg Hinderling

  • Zoom system
    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.
