A method for producing a shaped glass article may include heating at least a portion of a mold-facing surface of the glass article to a forming temperature, shaping the glass article in a mold, and removing the multilayer coating from the glass article. The glass article may be coated with a multi-layer removable coating including an inner layer in contact with the glass article and an outer layer disposed over the inner layer. The mold may be in direct contact with the outer layer during shaping. The inner layer may include a first glass having a softening point of at least about 50 C. less than a softening point of the glass article. The outer layer may include a second glass having a softening point of at least about 50 C. greater than the softening point of the glass article.

A coated article includes a glass substrate supporting a coating. The coating may include, moving away from the glass substrate, a layer comprising diamond-like carbon (DLC); a layer comprising zinc oxide, wherein a concentration of OH-groups at a surface of the layer comprising zinc oxide farthest from the glass substrate is no greater than about 40%; and a layer comprising aluminum nitride on the glass substrate over and directly contacting the layer comprising zinc oxide. The DLC layer may be temporary, and designed to be burned off during heat treatment.

The present invention is an antireflective film, including: a support base, and a pattern composed of a photoresist material formed on the support base, the index at a point closer to the support base. The present invention provides an antireflective film that is able to give antireflection effect to decrease the reflection of light, a method of producing the same, and an eyeglass type display.

The invention relates to a heatable glazing comprising an electrically conductive coating and a data transmission window. The data transmission window comprises a plurality of grids made by ablations in the electrically conductive coating and at least one break line between adjacent grids. At least one of a width a of the grids and a distance b between adjacent grids is selected to maximise transmission of a predetermined frequency of electromagnetic radiation and to reduce the formation of hot spots. Preferred embodiments conform to a standard size of an ERTICO window and a frequency range from 5 GHz to 6 GHz.

A method is provided for producing a glass ceramic element with a patterned coating is provided. The method includes: providing a glass ceramic element with a coating which is at least partially light-blocking and preferably opaque in the visible spectral range; irradiating the glass ceramic element with a pulsed laser beam on the face provided with the coating so that the coating is removed by ablation; during irradiating the laser beam is directed over the surface of the glass ceramic element so that a portion of the coating is removed which has a greater lateral extent than the diameter of the laser beam; and once the coating has been removed, irradiating the glass ceramic with the laser in the region where the coating has been removed, thereby optically modifying the glass ceramic in the irradiated region.

A Fresnel lens includes a Fresnel lens body, grooves formed on the lens surface of the Fresnel lens body and having bottom surfaces and inclined surfaces and a light absorber formed over the inclined surfaces and the bottom surfaces in which a contact angle at an end portion of the light absorber with respect to the bottom surface is larger than 70 degrees is used. A method of forming a film of a lens includes coating inclined portions of a plurality of grooves formed on a lens surface with ink, fixing the ink and removing unnecessary portions of the ink by laser.

The present disclosure relates to display, windows, camera cover, lens and lens cover, optical/infra-red sensors, glasses and spectacles.

A method to transfer a layer of harder thin film substrate onto a softer, flexible substrate. In particular, the present invention provides a method to deposit a layer of sapphire thin film on to a softer and flexible substrate e.g. quartz, fused silica, silicon, glass, toughened glass, PET, polymers, plastics, paper and fabrics. This combination provides the hardness of sapphire thin film to softer flexible substrates

A method for forming a glass container having a low-friction coating is provided. method includes contacting a glass tube with a coupling agent solution to form a coated glass tube having a coupling agent layer, wherein the coupling agent includes an inorganic material, contacting the coated glass tube with at least one sacrificial material to form a sacrificial layer at least partially covering the coupling agent layer, subsequent to contacting the coated glass tube with at least one sacrificial material, forming at least one coated glass container from the coated glass tube, the at least one coated glass container including the coupling agent layer, ion exchange strengthening the at least one coated glass container in an ion exchange salt bath, and applying a polymer chemical composition solution to the at least one coated glass container to form a low-friction coating.

A process for obtaining a material including a glass sheet, includes providing a glass sheet including a first face coated at least partly by an essentially mineral first coating, the face having at least one first zone and at least one second zone, the at least one first zone having a higher emissivity than that of the second zone, then applying, on at least one portion of the second zone, a sacrificial layer including a resin, then heat treating the coated glass sheet at a temperature of at least 550? C., during which step the sacrificial layer is removed by combustion.
