| titleOfInvention | TRANSPARENT AND SEMI-TRANSPARENT DIFFRACTION ELEMENTS, IN PARTICULAR HOLOGRAM, AND METHODS OF THEIR MANUFACTURE |
| abstract | The invention describes transparent and translucent diffraction elements, in particular holograms with a diffraction pattern formed in at least one of the following two layers with a different refractive index: a transparent carrier layer (1) of a polymer or copolymer with a refractive index n < 1.7, and enhancing the holographic effect, for which the refractive index is n> 1.7, the second layer (2), consisting of substances based on chalcogenides, containing at least one element from the group of elements consisting of sulfur, selenium a tellurium. The invention also discloses methods for manufacturing such products. According to one of them, the first diffraction pattern is formed in the carrier layer (1), after which a second layer (2) with a high refractive index is applied to this layer and a second diffraction pattern is formed in the second layer, while the substances of the second layer, which are chalcogenides with different composition applied simultaneously or sequentially. According to another method, a second layer (2) with a high refractive index is applied to the transparent carrier layer (1), and then the first diffraction pattern is mechanically formed in this layer and / or in both layers, and then a second diffraction pattern is formed in the second layer. |
