Patent number: 11579351Abstract: A flexible light guide that has a homogeneous light emission with high luminance is provided. The flexible light guide is provided by a side-emitting light guide. The side-emitting light guide includes a light-guiding fiber designed as a side-emitting fiber so that light guided in the fiber is scattered out along a longitudinal direction in a distributed manner. The guide also includes a tube that surrounds the fiber. The tube is designed to be light-scattering and translucent so that light emitted from the fiber can traverse the tube with scattering. The tube is surrounded by a cladding. The tube and cladding are made of plastic.Type: GrantFiled: September 4, 2020Date of Patent: February 14, 2023Assignee: SCHOTT AGInventors: Markus Kappel, Lothar Willmes, Hubertus Russert, Bernd Hoppe

Patent number: 11520096Abstract: A light source with a linear appearance is provided. The light source has a flexible light guide that has a homogeneous light emission with high luminance and a emitting light guide. The light emitting guide has a core, in which at least one soul extends, and a transparent cladding that surrounds the core. The core and the cladding are formed from transparent plastic. The core has a higher index of refraction than the cladding. The soul is light-deflecting, light-reflecting, or light-scattering so as to scatter light guided in the light guide and to emit the light through the cladding toward the outside. The soul has a scattering length that is at most twice as large as a maximum cross-sectional dimension of the soul.Type: GrantFiled: September 4, 2020Date of Patent: December 6, 2022Assignee: SCHOTT AGInventors: Markus Kappel, Bernd Hoppe, Hubertus Russert, Lothar Willmes

Patent number: 11510553Abstract: The disclosure relates to diagnostic, surgical, and/or therapeutic devices for being introduced into the human or animal body or for in vitro examination of human or animal blood samples or other body cells, in particular to an endoscope or a disposable endoscope that includes at least one illumination light guide and/or image guide for transmitting electromagnetic radiation, the illumination light guide or image guide having a proximal end face for incoupling or outcoupling of electromagnetic radiation and a distal end face for incoupling or outcoupling of electromagnetic radiation. The proximal and/or distal end faces consist of plastic elements that are transparent at least partially or in sections thereof, the transparent plastic being biocompatible and/or having non-toxic properties to human or animal cell cultures for exposure durations of less than one day. This allows for the production of assemblies for disposable endoscopes, inter alia.Type: GrantFiled: September 29, 2020Date of Patent: November 29, 2022Assignee: SCHOTT AGInventors: Bernd Schultheis, Björn Bleisinger, Andreas Dietrich, Markus Kappel, Hubertus Russert, Martin Cramer, Thomas Weingärtner

Publication number: 20210093170Abstract: A light guide is provided that includes a fiber bundle, a jacket, a proximal end, a distal end, and a terminated end face. The fiber bundle has a plurality of optical fibers. The jacket encloses at least a part of the plurality of optical fibers and/or the fiber bundle. The jacket has a maximum outer lateral dimension that is greater than a maximum outer lateral dimension of the fiber bundle by at most 500 ?m. The terminated end face is on the proximal end and/or the distal end. The terminated end face has a maximum lateral outer dimension that is not larger than the maximum outer lateral dimension of the jacket.Type: ApplicationFiled: September 25, 2020Publication date: April 1, 2021Applicant: SCHOTT AGInventors: Bernd Schultheis, Martin Cramer, Hubertus Russert, Holger Werner, Lukas Walter, Hildegard Voigt, Markus Kappel, Erwin Steiger

Patent number: 9075214Abstract: Sheathed optical waveguides and methods for producing such waveguides are provided. The sheathing is provided so that the fibers of the waveguides do not adhere to the sheathing. To this end, elastomeric material is formed into a tube surrounding a bundle of fibers and is solidified. The tube is prevented from radial compressing the fibers during solidification of the elastomeric material by a fluid in the tube.Type: GrantFiled: September 27, 2012Date of Patent: July 7, 2015Assignee: SCHOTT AGInventors: Bernd Schultheis, Markus Kappel

Patent number: 7760977Abstract: Step-index optical waveguides are made of multicomponent glass containing a core glass and an outer glass which entirely surrounds the core class. A fiber-optic cable for conducting electromagnetic radiation, contains at least one bundle of individual fibers which encompass the step-index optical waveguides that are made of multicomponent glass containing a core glass and an outer glass that entirely surrounds the core glass on the circumferential wall thereof. These step-index optical waveguides provide great transmission capacity for transmitting data while keeping the transfer characteristics sufficiently durable. Furthermore, the fiber-optic cable is resistant against physical and chemical environmental influences and be protected against radical ambient chemicals.Type: GrantFiled: September 15, 2008Date of Patent: July 20, 2010Assignee: Schott AGInventors: Axel Curdt, Lothar Willmes, Wolfgang Eis, Markus Kappel, Thomas Weingärtner, Thomas Henrich, Wolfram Gehenn, Uwe Kolberg
