According to one embodiment, a method for producing a coated glass article may include applying an anti-reflective coating onto a glass substrate. The glass substrate may include a first major surface, and a second major surface opposite the first major surface. The anti-reflective coating may be applied to the first major surface of the glass substrate. A substrate thickness may be measured between the first major surface and the second major surface. The glass substrate may have an aspect ratio of at least about 100:1. The coated glass article may have a reflectance of less than 2% for all wavelengths from 450 nanometers to 700 nanometers. The anti-reflective coating may include one or more layers. The cumulative layer stress of the anti-reflective coating may have an absolute value less than or equal to about 167,000 MPa nm.

The invention is directed to a method for finishing alkaline earth metal fluoride optical components and to the alkaline earth optical elements produced using the method. In particular, in the last polishing step, the method of the invention uses a colloidal silica polishing slurry having containing silica particles having a particle size of &#x3c;500 nm. Additionally, after colloidal silica polishing, the method using a megasonic cleaning step with a high pH detergent cleaning solution to remove any silica residue on the polished optical component. The optic resulting from use of the method has a polished and unetched surface roughness of less than 0.5 nm; a surface roughness of less then 0.6 nm after polishing and etching; and a step height of less than 6 nm.

A glass article having an anti-glare surface. The anti-glare surface has a distinctness-of-reflected image of less than 95, and a haze of less than or equal to 50%. In one embodiment, the glass article further includes a smudge-resistant surface disposed on the anti-glare surface. Methods of making the glass article and anti-glare surface are also described.

Glass having anti-glare surface and method of making

A method of making a 3D glass article includes forming at least one marker on an edge of a 2D glass piece. The 2D glass piece is thermally reformed into a 3D glass article, where the at least one marker formed on the edge of the 2D glass piece is carried over to an edge of the 3D glass article. The 3D glass article is aligned on a support using the at least one marker on the edge of the 3D glass article. Then, the edge of the 3D glass article is finished to a final shape and dimension.

Method and apparatus for making a 3D glass article

A method of screen printing on 3D glass articles includes providing a 3D glass article having a first 3D surface with a first surface profile and a second 3D surface with a second surface profile, the first 3D surface and the second 3D surface being separated by a thickness of glass. The method includes providing a fixture having a 3D fixture surface with a fixture surface profile matching the second surface profile. The method includes providing a screen having a design, a squeegee, and an ink. The 3D glass article is supported on the fixture by mating the second 3D surface with the 3D fixture surface. The screen is positioned at a plane a distance above the first 3D surface. The ink is deposited on the screen. The squeegee is positioned at a selected orientation relative to the plane. The ink is pushed through the screen onto the first 3D surface by simultaneously contacting the squeegee with the screen, traversing the squeegee in a linear direction, maintaining the orientation of the squeegee relative to the plane, locally deflecting the screen from the plane to the first 3D surface, and locally conforming the screen to the first surface profile.

Methods for extracting strengthened glass substrates from glass sheets are described herein. In one embodiment, the method for extracting strengthened glass substrates from glass sheets comprises forming a plurality of channel segments in the glass sheet. The plurality of channel segments may extend through the thickness of the glass sheet and are separated by remnant glass webs connecting the glass substrate to the glass sheet. The plurality of channel segments extend around a perimeter of the glass substrate. Thereafter, the glass sheet is strengthened by ion-exchange. The glass substrate is then separated from the glass sheet by severing the glass substrate from the remnant glass webs.

A glass article having an edge of which at least a portion that is ground and subsequently etched to provide a roughened edge. The roughened edge scatters light, thus enabling the glass article to be properly aligned. In some embodiments, the roughened edge also provides a surface having a coefficient of friction that facilitates handling of the glass article. The edge may further include at least one chamfer that may either be polished, so as to be transparent or ground and subsequently etched.

Low expansion glass material having low expansivity gradient

A glass article having at least one edge of which at least a portion has been laser melted. The laser melted portion scatters light, thus enabling the glass article to be properly aligned. In some embodiments, the laser melted portion also provides a roughened edge having a coefficient of friction that facilitates handling of the glass article. The laser melted portion is formed by irradiating the peripheral surface with a laser beam to cause localized melting.
