    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: A transparent wear-resistant, in particular scratch and/or impact-resistant, element is provided. The element includes a substrate, a layer system on a first surface of the substrate, and a reflectance at a second surface of the substrate of 2% in a visible spectral range of wavelengths from 380 nm to 780 nm. The glass or glass ceramic substrate is transparent in the visible spectral range. The layer system has two successive layers deposited on the first surface, where the two successive layers are each made of inorganic compounds. The two successive layers include a first layer with a first refractive index (n1) and a second layer with a second refractive index (n2), where the second refractive index (n2) is a value of at least 1.60. The first refractive index (n1) is greater than the second refractive index (n2) and a difference of the first and second refractive indices (n1−n2) is at least 0.05.

    Abstract: An optical layered composite includes: a substrate having a front face, a back face, a thickness ds between the front face and the back face, and a refractive index ns; and a coating applied to the front face, the coating having two regions, the two regions being a region A and a region B. The region A comprises one or more coating layers, each of which satisfies one or both of the criteria: a thickness below 5 nm; or a refractive index of 1.6 or more. The region B comprises one or more coating layers, each of which satisfies one or both of the criteria: a thickness below 5 nm; or a refractive index below 1.6.

    Abstract: A substrate is provided with an abrasion resistance antireflection coating. The coated substrate includes a multilayer antireflection coating on at least one side. The coating has layers with different refractive indices, wherein higher refractive index layers alternate with lower refractive index layers. The layers having a lower refractive index are formed of silicon oxide with a proportion of aluminum, with a ratio of the amounts of aluminum to silicon is greater than 0.05, preferably greater than 0.08, but with the amount of silicon predominant relative to the amount of aluminum. The layers having a higher refractive index include a silicide, an oxide, or a nitride.
