Abstract: The invention relates to an optical article, for example, an ophthalmic lens, comprising at least one multilayer anti-reflective coating on a transparent substrate made from organic or mineral glass. Said coating comprises successively and starting at the substrate, a layer of material with high refractive index (HI), made from a hybrid organic/inorganic matrix within which are dispersed particles of mineral oxide or chalcogenide with a diameter of 2 to 50 nm and a layer of material with low refractive index (BI), obtained by hardening of a composition comprising at least one silane precursor (I) with 4 hydrolysable groups and at least one fluorosilane precursor (II), said second composition comprising at least 10% in mass of fluorine in a theoretical dry extract and with a molar ratio I/I+II greater than 80%.

Abstract: The method involves forming a polarizing layer structure (30), with a orientation layer, on a film support (31), and placing a ophthalmic glass (40) and the structure between support surface pressing and inflatable pressing devices (10, 20). A portion of an adhesive material is arranged between the structure and the glass. The structure is pressed against a surface of the glass by inflating a membrane of the device (20) and by maintaining a fixed space between the devices. The ophthalmic glass is released and the support is withdrawn so that the structure is stick on the surface. Independent claims are also included for the following: (1) a layer structure comprising a orientation layer (2) a polarizing optical element comprising an optical base element and a layer structure.

Abstract: Une structure en couches polarisante (30) est réalisée sur un support temporaire (31). La structure comprend au moins une couche d'orientation (34) et une couche polarisante (35) à colorants dichroïques, les colorants dichroïques ayant une orientation angulaire déterminée par la couche d'orientation. La structure en couches est séparée du substrat temporaire avant d'être appliquée sur une surface d'un élément optique. L'application de la structure sur l'élément optique peut être effectuée aisément tout en obtenant une qualité compatible avec de nombreuses utilisations de l'élément optique, en particulier des utilisations ophtalmiques.

Abstract: Un élément optique polarisant est réalisé en formant d'abord une structure en couches polarisante (30) sur un support (31). La structure comprend une couche d'orientation et une couche polarisante à composés dichroïques, les composés dichroïques étant orientés par la couche d'orientation. La structure en couches est alors pressée contre une surface de l'élément optique (40), à travers le support, avec une portion de matériau adhésif disposée entre la structure et l'élément optique. Le support (31) de la structure est ensuite retiré, en laissant la structure (30) collée sur l'élément optique (40).
