Patent number: 10611662Abstract: A method for the production of glass components, an apparatus for carrying out the method, and a glass component that is obtainable through the method are provided. The method is a drawing method wherein a forming zone of a preform is heated to a temperature that allows drawing of the glass. The method includes a forming zone of the preform that is very small. Thereby the width of the preform is decreased to a smaller extent than its thickness. The glass components that can be obtained by this method have very smooth surfaces.Type: GrantFiled: May 3, 2017Date of Patent: April 7, 2020Assignee: SCHOTT AGInventors: Frank Buellesfeld, Ulrich Lange, Ralf Biertuempfel, Lisa Pudlo, Helge Jung

Patent number: 9815734Abstract: Optical glass filters are provided that include a filter glass showing an optimized transmission spectrum which has a high transmission in the wave length range of 300 to 400 nm and a very low transmission in the visible wave length range. The glass has an especially high optical quality and is excellently suitable as an optical filter for generating UV light without a proportion of visible light. The optical glass filters include the components nickel oxide and cobalt oxide.Type: GrantFiled: December 11, 2015Date of Patent: November 14, 2017Assignee: SCHOTT AGInventors: Lothar Niessner, Ralf Biertuempfel

Patent number: 9752756Abstract: A lighting device is provided that includes an LED and an NIR filter for a control panel or a display, which does not interfere with a night vision device. The light of the LED is in an area of u?>0.19 and v?>0.46 of the u?v? diagram of the CIE-LUV chromaticity diagram. The NIR filter exhibits descending light transmittance between 500 nm and 800 nm. The thickness of the NIR filter is chosen so that a sufficient blocking effect is provided in a range of wavelengths between 600 nm and 800 nm, so that the color coordinates of the filtered useful light are in an area with a radius of 0.04 around coordinates u?=0.19 and v?=0.49 of the u?v? diagram.Type: GrantFiled: October 7, 2014Date of Patent: September 5, 2017Assignee: SCHOTT AGInventors: Ralf Biertuempfel, Steffen Reichel, Michael Landi
