Abstract
(EN)
Provided are: a Fresnel lens that can inhibit generation of a flare which extends toward the center of the lens in an image viewed through Fresnel lenses; and a manufacturing method for the Fresnel lens. In the present invention, a lens surface (24) and a non-lens surface (26) are formed in each of lens portions (22). The non-lens surface (26) includes a rise surface (26a) and a connection surface (26b). The rise surface (26a) extends along the optical axis of a Fresnel lens (1). The connection surface (26b) is formed on an apex (22a) of each of the lens portions (22), connects the lens surface (24) of the lens portion (22) to the rise surface (26a) of the lens portion (22), and has a width extending in the radial direction of the Fresnel lens (1). A light absorption portion (12) is provided at a position along the optical axis, of the Fresnel lens (1), passing the connection surface (26b).

L'invention concerne: une lentille de Fresnel capable d'inhiber la génération d'une lumière parasite qui s'étend vers le centre de la lentille dans une image vue à travers des lentilles de Fresnel; et un procédé de fabrication pour la lentille de Fresnel. Dans la présente invention, une surface (24) de lentille et une surface (26) hors lentille sont formées dans chacune des parties (22) de lentille. La surface (26) hors lentille comprend une surface (26a) d'élévation et une surface (26b) de raccordement. La surface (26a) d'élévation s'étend suivant l'axe optique d'une lentille (1) de Fresnel. La surface (26b) de raccordement est formée sur un sommet (22a) de chacune des parties (22) de lentille, relie la surface (24) de lentille de la partie (22) de lentille à la surface (26a) d'élévation de la partie (22) de lentille, et présente une largeur s'étendant dans la direction radiale de la lentille (1) de Fresnel. Une partie (12) d'absorption de lumière est placée dans une position, le long de l'axe optique de la lentille (1) de Fresnel, dépassant la surface (26b) de raccordement.
