The invention is also directed to a method of removing the quasi-Bielby layer formed when a shaped optical element is polished. Removal of the quasi-Bielby layer prior to coating results in improved durability and optical transmission characteristics of the coated lenses. The coating material can be any material that does not impede the transmission of below 250 nm electromagnetic radiation. Fluorine doped silicon dioxide is the preferred coating material.Type: GrantFiled: August 31, 2004Date of Patent: October 31, 2006Assignee: Corning IncorporatedInventors: Robert L Maier, Jue Wang

Patent number: 7083846Abstract: A ceramic member, which is usable in a state where at least a part thereof is exposed in a reactor in which halogen plasma is generated, includes a base member containing a first ceramic material, and a coating layer on a surface of the base member containing a second ceramic material more resistant to plasma etching than the first ceramic material. Further, the ceramic member includes a thick portion in a region where an etching rate of the coating layer by the halogen plasma is locally high, and a thickness (tt) of the thick portion and a thickness (tn) of a normal thickness portion other than the thick portion satisfy the following expression (1): tn<tt?(Ee/En)×tn??(1) where En: etching rate of the coating layer in the normal thickness portion; and Ee: etching rate of the coating layer in the thick portion.Type: GrantFiled: March 9, 2004Date of Patent: August 1, 2006Assignee: NGK Insulators, Ltd.Inventor: Hirotake Yamada

Patent number: 6994885Abstract: The invention provides an optical filter comprising: a. an organic, solar blind filter dye; and b. a UV-transparent, non-scattering and chemically stable substrate. The substrate may be a UV-transparent nanoporous silica glass solid having pores that are substantially filled with a UV-transparent solvent, which has been selected to dissolve said dye and also to match the refractive index of the nanoporous silica glass solid. Alternatively, the substrate may be a UV-transparent inorganic salt compressed to form a solid body. The invention also provides for methods of making these embodiments and an optical device comprising such an optical filter. The filter provides an efficient solar blind filter that is chemically and dimensionally stable.Type: GrantFiled: November 3, 2004Date of Patent: February 7, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventors: Richard G. S. Pong, Steven R. Flom, James S. Shirk

Patent number: 6881491Abstract: An aluminum alloy article is cleaned to remove oxides and organic matter from a coatable surface, coated with a composition comprising an organic resin and a fluorine compound, and then heated to an elevated temperature to decompose the organic resin and at least a portion of the fluorine compound. After heating the coated surface is left with a protective oxyfluoride film that prevents blistering and hydrogen pickup and promotes hydrogen degassing from the article.Type: GrantFiled: May 16, 2003Date of Patent: April 19, 2005Assignee: Alcoa Inc.Inventors: Sally A. Jankosky, Susanne M. Opalka, Paula L. Kolek, Joseph P. Harenski, Roger W. Kaufold, Larry F. Wieserman
