Abstract[English]
An ophthalmic lens defining an optical axis can include: a plurality of annular regions extending in a radial direction away from the optical axis, including a corresponding plurality of echelettes, wherein the plurality of echelettes forms an echelette profile, wherein each the echelette profile includes a staircase profile, wherein each echelette includes a staircase step, wherein, for each staircase step, there are M phase-shift units arranged vertically, wherein M is an integer, wherein each phase-shift unit has a phase height configured to shift the phase of a reference frequency of light by approximately N*2*π, where N is an integer, and wherein the staircase profile forms an irregular staircase.[French]
L'invention concerne une lentille ophtalmique définissant un axe optique qui peut comprendre : une pluralité de régions annulaires s'étendant dans une direction radiale à l'opposé de l'axe optique, comprenant une pluralité correspondante d'échelettes, la pluralité d'échelettes formant un profil d'échelette, chaque profil d'échelette comprenant un profil d'escalier, chaque échelette comprenant une marche d'escalier, pour chaque marche d'escalier, il y a M unités de déphasage agencées verticalement, M étant un nombre entier, chaque unité de déphasage ayant une hauteur de phase configurée pour décaler la phase d'une fréquence de référence de lumière d'approximativement N*2*π, N étant un nombre entier, et le profil d'escalier formant un escalier irrégulier.
