Abstract: The invention relates to a method for producing an optical article having antireflection or reflective properties and comprising a substrate having at least one main surface, comprising the step of depositing an sub-layer onto a substrate's main surface, the step of treating the sub-layer by ionic bombardment and the step of depositing onto said sub-layer a multilayered stack comprising at least one high refractive index layer and at least one low refractive index layer. According to a preferred embodiment, the deposition of the sub-layer is conducted in a vacuum chamber in which a gas is supplied during the deposition step.

Abstract: Disclosed is a method for marking an optical article coated with an interference coating including at least two layers, an inner layer and an outer layer, and having reflection coefficient Re; by exposure of the inner layer, at a marking point, by way of a laser beam at a marking wavelength, in such a way as to ablate the inner layer and any layer further away from the substrate; the ablated area having a reflection coefficient Rm different from Re by at least 1%; the inner layer absorbing the marking wavelength to a greater degree than any layer further away from the substrate. Also disclosed is an optical article coated with an interference coating having at least two layers, an inner layer and an outer layer, the article including a marking pattern formed by local absence of layers.
