Summary:A diffractive optical element (10) is constituted by sandwiching and closely bonding first and second optical elements (13, 14), which have different refractive indexes and are adhered through a relief pattern (20), between third and fourth optical elements (11, 12). L'invention concerne un élément optique à diffraction (10) qui est obtenu suite au serrage en sandwich et au liaisonnement étroit des premier et deuxième éléments optiques (13, 14), lesquels possèdent différents indices de réfraction, et sont collés l'un à l'autre par un motif en creux (20), entre les troisième et quatrième éléments optiques (11, 12).
