Abstract: front page image
(EN)A method of fabricating an aspherical gradient refractive index lens includes co-extruding a first polymer material having a first refractive index and a second polymer material having a second refractive index different than the first refractive index to form multilayered polymer composite films, assembling the multilayered polymer composite films into a multilayer composite GRIN sheet and shaping the multilayered composite GRIN sheet into an aspherical lens.
(FR)L'invention concerne un procédé de fabrication d'une lentille asphérique à gradient d'indice de réfraction, comprenant la coextrusion d'un premier matériau polymère présentant un premier indice de réfraction et d'un second matériau polymère présentant un second indice de réfraction, différent du premier indice de réfraction, pour former des films polymères composites multicouches, l'assemblage des films polymères composites multicouches pour obtenir une feuille composite multicouche GRIN et la mise en forme de la feuille composite multicouche GRIN pour obtenir une lentille asphérique.
