Abstract:
The invention relates to a method for preparing an optical system item having a non-zero radius of curvature and coated with an interference coating. Said method includes: a) providing a thermoplastic film coated with a multilayer interference coating containing at least one layer having a refractive index of greater than 1.65 and at least one layer having a refractive index of less than or equal to 1.65, at least one of the interference coating layers being a vacuum-deposited organic/inorganic layer, b) laminating said coated thermoplastic film, by means of an adhesive layer, onto an optical system item including a substrate, and c) recovering said optical system item, including a substrate coated with the adhesive layer, from the thermoplastic film and the multilayer interference coating.

Claim (Index 18):
An optical article having a non-zero radius of curvature comprising a substrate on which a layer of adhesive, a thermoplastic film and a multilayer interference coating are deposited, said thermoplastic film adhering to the surface of the lens by means of said layer of adhesive positioned between the optical article and the surface of the thermoplastic film not coated with interference coating, said interference coating comprising at least one layer having a refractive index of greater than 1.65 and at least one layer having a refractive index of less than or equal to 1.65, at least one of the layers of the interference coating being a layer of organic-inorganic nature that has been deposited under vacuum.
