Processes of chamfering and/or beveling an edge of a glass substrate of arbitrary shape using lasers are described herein. Two general methods to produce chamfers on glass substrates are the first method involves cutting the edge with the desired chamfer shape utilizing an ultra-short pulse laser to create perforations within the glass; followed by an ion exchange.

Edge chamfering methods

A strengthened glass article having a central tension that is below a threshold value above which the glass exhibits frangible behavior. The central tension varies non-linearly with the thickness of the glass. The glass article may be used as cover plates or windows for portable or mobile electronic devices such as cellular phones, music players, information terminal (IT) devices, including laptop computers, and the like.

Strengthened glass articles and methods of making

A method of chemically strengthening a glass. The method includes ion exchange of the glass in a first bath, followed by immersion in the second bath. The first bath is diluted with an effluent ion. The second bath has a smaller concentration of the effluent ion than the first bath. The method provides a compressive stress at the surface of the glass that is sufficient to arrest flaws introduced by contact forces at the surface of the glass while having sufficiently deep compressive depth-of-layer for high reliability.

Dual stage ion exchange for chemical strengthening of glass

A substrate includes an opaque chrome coating on a surface of the substrate dry-etched to form an aperture, wherein chrome in the aperture is below detectable limit. A method of forming an opaque chrome coating on a substrate includes depositing an initial thickness of the opaque chrome coating on the substrate without ion-assist or with undetectable ion-assist and depositing the remainder of the opaque chrome coating with or without ion-assist. In one embodiment the invention is directed to an apertured optical element having a substrate transmissive to light and an opaque chrome coating on the substrate defining an aperture. Three- and four-layer opaque coatings of various materials are disclosed, including three-layer chrome/chrome oxide/chrome coatings.

A method for producing lenses includes assembling a plurality of glass rods having a desired length into a single unit and cutting the single unit into multiple slices, each slice having a plurality of individual lenses. The method further includes finishing the slices to a desired thickness and surface finish and extracting the individual lenses from the slices.

Multi-lens finishing process

The present invention relates to a glass envelope for an illuminating device, the glass envelope comprising a gas channel, a pair of electrodes in communication with the gas channel and a glow-discharge lamp as a source of free electrons coupled to the glass envelope to assist the starting of the illuminating device in dark conditions, for example at night. Preferably, the glass envelope has a front and back surface laminated and integrated together to form a unitary body essentially free of any sealing materials.
