OPTICAL SECURITY COMPONENT VISIBLE IN REFLECTION, MANUFACTURE OF SUCH A COMPONENT, AND SECURE DOCUMENT PROVIDED WITH SUCH A COMPONENT
(FR)
COMPOSANT OPTIQUE DE SECURITE VISIBLE EN REFLEXION, FABRICATION D'UN TEL COMPOSANT ET DOCUMENT SECURISÉ EQUIPÉ D'UN TEL COMPOSANT
Abstract:
(EN)
According to one aspect, the invention relates to an optical security component intended to be observed in reflection, by the naked eye, along an observation face. It comprises a first layer made from dielectric material, having a first refractive index (ni), at least one first diffractive structure (S
1
, S
2
) being etched on said first layer, and a second layer at least partially covering said first structure, and having a spectral reflection band in the visible spectrum. The first structure comprises a first pattern with at least one set of modules arranged side by side, in a given arrangement direction (X), wherein a maximum width (λ) of each module defined in the arrangement direction (X) is less than 300 μm. Each module comprises a low-relief with a first set of facets, the shapes of which are determined to simulate an optical element visible in reflection, with at least one convex or concave region, having a profile with a slope that is variable in a single direction (Y), referred to as the slope variation direction, perpendicular to the arrangement direction (X). Furthermore, the first pattern is modulated by a second pattern forming a periodic grating having a period of between 100 nm and 700 nm, determined to produce, after deposition of the second layer, a resonant filter that resonates in a given spectral resonance band, such that, for two modules arranged side by side, said two modules have different spectral resonance bands.
(FR)
Selon un aspect, l'invention concerne un composant optique de sécurité destiné à être observé en réflexion, à l'œil nu, selon une face d'observation. Il comprend une première couche en matériau diélectrique, présentant un premier indice de réfraction (ni), au moins une première structure (S
1
, S
2
) diffractive gravée sur ladite première couche et une deuxième couche, recouvrant au moins en partie ladite première structure, et présentant une bande spectrale de réflexion dans le visible. La première structure comprend un premier motif avec au moins un ensemble de modules disposés côte à côte, selon une direction (X) d'agencement donnée, une largeur maximale (λ) de chaque module définie dans la direction d'agencement (X) étant inférieure à 300 μm. Chaque module comprend un bas-relief avec un premier ensemble de facettes dont les formes sont déterminées pour simuler un élément optique visible en réflexion, avec au moins une région convexe ou concave, présentant un profil avec une pente variable selon une seule direction (Y), dite direction de variation de la pente, perpendiculaire à la direction d'agencement (X). Par ailleurs, le premier motif est modulé par un deuxième motif formant un réseau périodique de période comprise entre 100 nm et 700 nm, déterminé pour produire, après dépôt de la deuxième couche, un filtre résonant dans une bande spectrale de résonance donnée, de telle sorte que pour deux modules disposés côte à côte, la bande spectrale de résonance est différente entre lesdits deux modules.
