Abstract

La présente invention a pour objet un élément optique doté d'effets anti-reflet améliorés, notamment dans une structure à rainures profondes ayant un pas de 1,5 μm ou plus et des surfaces inclinées sur les côtés. Sur un premier corps moulé (2), un motif de diffraction (5) composé d'une section en saillie (6) et d'une section en retrait (7) est formé. Le pas (H1) entre la section en saillie (6) et la section en retrait (7) est égal ou supérieur à 1,5 μm. Grâce à une surface inclinée (10) permettant d'améliorer la facilité de démoulage et agencée dans une partie proche d'au moins une surface inférieure de la section en retrait (7a) entre une surface supérieure de la section en saillie (6a) et la surface inférieure de la section en retrait (7a), le motif de diffraction d'une rainure profonde de 1,5 μm ou plus est formé de manière extrêmement précise, et une structure anti-reflet (8) composée de formes minces en saillie ou en retrait est formée sur la surface supérieure de la section en saillie (6a), la surface inférieure de la section en retrait (7a) et la surface inclinée (10). Ce système permet d'améliorer plus judicieusement les effets anti-reflet et d'améliorer judicieusement les performances du réseau de diffraction.
