    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 package for encapsulating a functional area against an environment includes a base substrate and a cover substrate, the base substrate together with the cover substrate defining at least part of the package or defining the package, and furthermore including the at least one functional area provided in the package, and a blocking way for reducing permeation between the environment and the functional area. The package may include at least one laser bonding line, and the substrates of the package can be hermetically joined to one another by the at least one laser bonding line, and the laser bonding line has a height (HL) perpendicular to its bonding plane.

    Abstract: The present disclosure relates to a layered optical composite, in particular for use in an augmented reality device. In particular, the disclosure relates to a layered optical composite and a process for its preparation, a device comprising the layered optical composite and a process for its preparation, and the use of a layered optical composite in an augmented reality device.
    The present disclosure relates to a layered optical composite comprising: a. a substrate having a front face and a back face, b. a coating comprising: i. a type T layer, and ii. a type C region comprising one or more type C layers; in which the substrate has: i. a thickness tG in the range from 0.2 to 1.2 mm; ii. a refractive index nG at a wavelength λ in the range from 1.6 to 2.4; and iii. an optical absorption coefficient KG at the wavelength λ of less than 10 cm−1; in which the type C layers individually and independently have: i. a thickness tC in the range from 9 to 250 nm; ii. a refractive index nC at the wavelength λ in the range from 1.35 to 2.43; and iii. an optical absorption coefficient KC at the wavelength λ of less than 106 cm−1; in which at least one type C layer has: i. an optical absorption coefficient at the wavelength λ of at least 100 cm−1; in which the type T layer has: i. a thickness tT in the range from 50 to 300 nm; ii. a refractive index nT at the wavelength λ in the range from 1.35 to 1.96; and iii. an optical absorption coefficient KT of less than 80 cm−1; in which the type C region and the type T layer are each superimposed over one face of the substrate with the type C region further than the type T layer from the substrate; in which λ is in the range from 430 to 670 nm.

    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.
