Publication number: 20240012197Abstract: The present disclosure relates to light isolating arrays (can also be called “light pipes” or “light pipe arrays”) that enable high transmission efficiency and isolation of light from one location, for example a lens, to another location, for example an array of photodetector diodes (each a “PD”). The light isolating arrays can provide optical isolation of the input light and can eliminate cross talk thus enhancing the resolution via increased contrast of the incoming signal. The light isolating arrays can also protect the PD's from contamination when used in outdoor devices.Type: ApplicationFiled: November 16, 2021Publication date: January 11, 2024Applicants: SCHOTT Corporation, SCHOTT AGInventors: Oliver Sohr, Sebastian Leugner, Kevin Tabor, Michael Dargie, Elisabeth Han

Patent number: 11713275Abstract: The present disclosure relates to compositions that can be used for optical fibers and other systems that transmit light in the near-, mid- and/or far-ranges of the infrared spectrum, such as for example in the wavelength range of 1.5 ?m to 14 ?m. The optical fibers may comprise a light-transmitting chalcogenide core composition and a cladding composition. In some embodiments, the light-transmitting chalcogenide core composition has a refractive index n(core) and a coefficient of thermal expansion CTE(core), and the cladding composition has a refractive index n(cladding) and a coefficient of thermal expansion CTE(cladding), wherein n(cladding) is less than n(core) and in some embodiments wherein CTE(cladding) is less than CTE(core). In some embodiments, the chalcogenide glass core composition comprises a) sulfur and/or selenium, b) germanium, and c) gallium, indium, tin and/or one or more metal halides.Type: GrantFiled: June 12, 2019Date of Patent: August 1, 2023Assignee: SCHOTT CORPORATIONInventors: Bernd Schultheis, Nathan Carlie, Lothar Willmes, Simone Monika Ritter, Bernd Hoppe, William James

Patent number: 11667579Abstract: The invention relates to a polycrystalline IR transparent material produced by sintering chalcogenide powder, e.g., ZnS powder, using hot uniaxial pressing followed by hot isostatic pressing. The microstructure of the material described in this disclosure is much finer than that found in material produced using the state of the art process. By using a powder with a particle size fine enough to improve sintering behavior but coarse enough to prevent a lowering of the wurtzite-sphalerite transition temperature, a highly transparent material with improved strength is created without degrading the optical properties. A high degree of transparency is achieved during hot pressing by applying pressure after the part has reached a desired temperature. This allows some degree of plastic deformation and prevents rapid grain growth which can entrap porosity. The crystallographic twins created during this process further inhibit grain growth during hot isostatic pressing.Type: GrantFiled: February 12, 2019Date of Patent: June 6, 2023Assignee: Schott CorporationInventors: Keith Gregory Rozenburg, Eric Hector Urruti

Publication number: 20210349258Abstract: An image-conducting optical fiber bundle extends along a central bundle axis between image input and image output ends. The bundle is twisted along a portion of its length such that an image inputted into the image input end is angularly displaced about the central bundle axis before being outputted through the image output end. Each constituent optical fiber includes a cladding with a cladding diameter corresponding with the fiber diameter of that fiber and a core with a core diameter. The ratio of the core diameter to the cladding diameter defines a core-to-clad diameter ratio relative to each fiber. In various embodiments, at least one of fiber diameter and core-to-clad diameter ratio varies as a function of a fiber's radial displacement from the central bundle axis.Type: ApplicationFiled: July 21, 2021Publication date: November 11, 2021Applicant: SCHOTT CorporationInventors: Kevin Tabor, Paige Higby, Paulette Onorato
