Abstract
An optical element comprises a base component () provided with a set of cells () open on a face of the component and a film () for sealing the cells. The film is adhesively bonded to ends () of separation walls () present between the cells. The adhesive bonding is carried out by applying a pressure adjusted so that the ends of the walls penetrate into a layer of adhesive material () positioned between the film and the set of cells. A refractive index value of the adhesive material is adjusted with respect to a value of the same index for the material of the ends of the walls m order to obtain an optical element which exhibits a high transparency.
