Patent number: 11143800Abstract: A highly reflective mirror for use in the wavelength range of 0.300 ?m to 15 ?m includes a substrate, a first interface layer, a reflective layer, a second interface layer, a plurality of tuning layers including a combination of a low index material and a high index material wherein the high index material is HfO2, and a protective layer. The highly reflective mirror has a reflectivity of at least 90% over the wavelength range of 335 nm to 1000 nm at an angle of incidence (AOI) of 45°.Type: GrantFiled: June 6, 2018Date of Patent: October 12, 2021Assignee: Corning IncorporatedInventors: Jason Scott Ballou, Gary Allen Hart, Leonard Gerard Wamboldt

Patent number: 10955594Abstract: The disclosure is directed to a highly reflective multiband mirror that is reflective in the VIS-NIR-SWIR-MWIR-LWIR bands, the mirror being a complete thin film stack that consists of a plurality of layers on a selected substrate. In order from substrate to the final layer, the mirror consists of (a) substrate, (b) barrier layer, (c) first interface layer, (d) a reflective layer, (e) a second interface layer, (f) tuning layer(s) and (g) a protective layer. In some embodiments the tuning layer and the protective layer are combined into a single layer using a single coating material. The multiband mirror is more durable than existing mirrors on light weight metal substrates, for example 6061-Al, designed for similar applications. In each of the five layer types methods and materials are used to process each layer so as to achieve the desired layer characteristics, which aid to enhancing the durability performance of the stack.Type: GrantFiled: March 9, 2018Date of Patent: March 23, 2021Assignee: Corning IncorporatedInventors: Jason S Ballou, Frederick J Gagliardi, Gary Allen Hart, Timothy R Soucy, Robin Merchant Walton, Leonard Gerard Wamboldt, Jue Wang

Patent number: 10605966Abstract: A method for coating substrates is provided. The method includes diamond turning a substrate to a surface roughness of between about 60 ? and about 100 ? RMS, wherein the substrate is one of a metal and a metal alloy. The method further includes polishing the diamond turned surface of the substrate to a surface roughness of between about 10 ? and about 25 ? to form a polished substrate, heating the polished substrate, and ion bombarding the substrate with an inert gas. The method includes depositing a coating including at least one metallic layer on the ion bombarded surface of the substrate using low pressure magnetron sputtering, and polishing the coating to form a finished surface having a surface roughness of less than about 25 ? RMS using a glycol based colloidal solution.Type: GrantFiled: February 22, 2018Date of Patent: March 31, 2020Assignee: Corning IncorporatedInventors: Joseph Charles Crifasi, Gary Allen Hart, Robin Merchant Walton, Leonard Gerard Wamboldt, Jue Wang

Patent number: 3964094Abstract: The position of a length of magnetic recording tape, adjacent a rotating head device, is servo controlled to accurately position a transverse tape data track in alignment with the head path. The tape includes two distinctive servo indicia. The first indicia is a magnetic flux transition which is oriented substantially parallel to the edge of the tape. The second indicia is a magnetic flux transition which is oriented at an angle to the edge of the tape. This second indicia is parallel to the magnetic flux transitions which comprise the data track, and said distinctive second indicia is provided for each data track to define the physical location thereof. The rotating head includes two head gaps, one of which is parallel to the first indicia, and the other of which is parallel to the second indicia. The head gaps angular relationship insures that the respective head gaps will read only that indicia which is parallel therewith.Type: GrantFiled: November 7, 1974Date of Patent: June 15, 1976Assignee: International Business Machines CorporationInventor: Gary Allen Hart
