Abstract:
Methods of improving the direct bonding of articles are disclosed. Lithium can be incorporated into the composition of one of the articles and/or lithium can be added to a bonding surface by ion exchange, absorption, ion implantation, coating, or deposition. Bonding is achieved without use of adhesives or high temperature fusion. The invention is useful for bonding a wide variety of articles together such as optical components, optical fibers and articles having different coefficients of thermal expansion or refractive indices.
Abstract:
A glass wafer (100) having a first major surface (110), a second major surface (120) that is parallel to and opposite of the first major surface (110), a thickness between the first major surface (110) and the second major surface (120), and an annular edge portion (130) that extends from an outermost diameter of the glass wafer (100) toward the geometrical center of the glass wafer (100). The glass wafer (100) has a diameter from greater than or equal to 175 mm to less than or equal to 325 mm and a thickness of less than 0.350 mm. A width of the edge portion (130) is less than 10 mm.
Abstract:
A glass sheet having enhanced edge strength. The glass sheet is down-drawn and has at least one laser-formed edge having a minimum edge strength of at least about 90 MPa. The laser-formed edge is substantially free of a chamfer or a bevel. The glass sheet can be strengthened after formation of the edge and is adaptable for use as a cover plate for display and touch screen applications, or as a display or touch screen for information-related terminal (IT) devices; as well as in other applications.
Abstract:
An alkali aluminosilicate glass article, said alkali aluminosilicate glass having a surface compressive stress of at least about 200 MPa, a surface compressive layer having a depth of at least about 30 µm, a thickness of at least about 0.3 mm and an amphiphobic fluorine-based surface layer chemically bonded to the surface of the glass. In one embodiment the glass has an anti reflective coating applied to one surface of the glass between the chemically strengthened surface of the glass and the amphiphobic coating. In another embodiment the surface of the chemically strengthened glass is acid treated using a selected acid (e.g., HCL, H 2 SO 4 , HClO 4 , acetic acid and other acids as described) prior to placement of the amphiphobic coating or the anti reflective coating.

Abstract:
The invention is directed to a method for cleaning surfaces of optical elements made from metal fluoride single crystals of formula MF2, where M is calcium, barium, magnesium, or strontium, or mixtures of the foregoing, prior to coating the elements with films of protective materials. The method has at least the steps of: (a) immersing the optical element in at least one selected liquid and utilizing sonication at megasonic frequencies to remove particulates, polishing slurry residue and the damaged top layer of the optical element; (b) cleaning in a gas phase cleaning process whereby hydrocarbons are removed from the surface of the optical element using UV/ozone cleaning; and (c) exposing, in a gas phase process, of the optical element's surface to a low-energy plasma containing argon and oxygen in a vacuum environment.
