Abstract: Glare-free glass articles and methods for producing are provided. The glass article includes a surface with an area having a roughness RMS from 10 nm to 1000 nm, a distinctness of image DOI from 30 to 70, a gloss value of less than 40 at a viewing angle of 60°, and a haze value, determined in transmission, of less than 3%. The area also has a ratio of mean height of peaks above core surface (Spk) to mean depth of valleys below core surface (Svk) that is equal to 1±0.1 within a measured surface area of more than 0.1 mm2 and less than 3 mm2.

Abstract: A coated substrate includes a substrate and a multilayered antireflective coating built up from layers having different refractive indices on at least one side of the substrate. Layers having a relatively high refractive index and layers having a relatively low refractive index alternate and at least one layer having a relatively low refractive index is composed of a composition X containing silicon oxide and zirconium oxide. A proportion of zirconium in a metallic and semiconducting component in the composition X is 0.2% to 10% by weight.

Abstract: A coated substrate is provided with a scratch-resistant anti-reflective coating. The anti-reflective coating is designed as an optical interference coating that has at least two low refractive index layers and at least one high refractive index layer. The high refractive index layer is a transparent hard material layer and includes crystalline aluminum nitride with a hexagonal crystal structure with a (001) preferred orientation. The low refractive index layers include SiO2. The low refractive index layers and high refractive index layers are arranged alternately.
Abstract translation: 涂覆的基底上设置有耐刮擦的抗反射涂层。 抗反射涂层被设计为具有至少两个低折射率层和至少一个高折射率层的光学干涉涂层。 高折射率层是透明硬质材料层，并且包括具有（001）优选取向的六方晶系结构的结晶氮化铝。 低折射率层包括SiO 2。 低折射率层和高折射率层交替排列。
