Abstract: A method for manufacturing an optical article including the following steps: a. providing a first substrate with a main surface, b. depositing a second substrate on the main surface with an adhesive layer so that the space between the first substrate and second substrate is filled by the adhesive layer, c. curing the adhesive layer to induce a polymerization of the adhesive layer, wherein a tension step takes place after steps a. and b., and before step c., the tension step including applying symmetrically a tension, preferentially with a central symmetry, preferentially a radial isotropic tension or an ortho-distributed symmetrical tension, on the edges of the second substrate sensibly in a tension plan parallel to a plan representative of the main surface.

Abstract: Method for encapsulating at least partly a light-guide optical element in a transparent capsule, the method comprising at least: —a transparent capsule providing step during which a transparent capsule is provided, —a light-guide optical element providing step during which a light-guide optical element is provided, —an adhesive deposing step during which an adhesive is deposited on at least part of a face of the transparent capsule and/or of a face of the light-guide optical element, —a positioning step during which the transparent capsule and the light-guide optical element are positioned one relative to the other so as to form an optical system, —a bonding step during which the light-guide optical element and the transparent capsule are made integral with the adhesive, wherein the method further comprises prior to the bonding step a control step during which at least one parameter of the optical system is controlled.
