Abstract: A transparent pane comprising a first optically active pattern in a first plane, and a second optically active pattern in a second plane, the second plane being positioned at a distance from the first plane in the direction of thickness of the pane.

Abstract: In a method for producing a biocidal glass surface of a soda-lime glass, a glass surface of a soda-lime glass is indirectly or directly contacted with silver, silver salt, or silver ions and directly or indirectly heated using at least one laser beam of a laser such that an ion exchange of sodium ions from the soda-lime glass with silver ions of the silver ions or from the silver or the silver salt results and silver ions of the silver ions deposit in the region of the glass surface. Before being heated, the glass surface is coated with a transfer support including a layer of silver and a protective layer covering the silver layer, such that the protective layer directly contacts the glass surface, the glass surface then being heated using the laser. Also, a soda-lime glass having a biocidal glass surface is produced by the method.

Abstract: A solar glass is specified. In an embodiment a solar glass includes a glass substrate and a layer system arranged on the glass substrate, wherein the layer system includes a base layer comprising one or more first dielectric layers, a first silver layer arranged on the base layer, an absorber layer arranged on the first silver layer, the absorber layer comprising a metal or metal alloy, an aluminum oxynitride layer arranged on the absorber layer, an intermediate layer arranged on the aluminum oxynitride layer, the intermediate layer comprising one or more second dielectric layers, a second silver layer arranged on the intermediate layer and a cover layer arranged on the second silver layer, the cover layer comprising one or more third dielectric layers, and wherein the absorber layer has a spatially varying thickness, a spatially varying material composition and/or a spatially varying surface coverage density in at least one direction.

Abstract: A method for producing a glass sheet is disclosed. In an embodiment a method includes applying a plurality of supporting bodies to the glass sheet, wherein applying the supporting bodies to the glass sheet includes performing a float glass process while producing the glass sheet, and wherein the supporting bodies are applied while the glass sheet has a temperature above a glass transition temperature so that the supporting bodies partially fuse with the glass sheet.
