Zusammenfassung:	The invention proposes a set of semi-finished lenses (10), each intended to be used in the manufacturing of a finished lens of determined target power, each semi-finished lens having a base curve (Bi) chosen among a number (N) of base curves, wherein each base curve (Bi) is associated to a respective range of powers of finished ophthalmic lenses to be manufactured, and each semi-finished lens of the set comprises a recorded holographic component (13), wherein the holographic components of the set exhibit a limited number of configurations, and each holographic component configuration (Hi) is associated exclusively to one base curve among the N base curves. The invention also proposed a method for manufacturing a set of semi-finished lenses and a lens from a semi-finished lens of the set. L'invention propose un ensemble de lentilles semi-finies (10), chacune destinée à être utilisée dans la fabrication d'une lentille finie d'une puissance cible déterminée, chaque lentille semi-finie ayant une courbe de base (Bi) choisie parmi un nombre (N) de courbes de base, chaque courbe de base (Bi) est associée à une plage respective de puissances de lentilles ophtalmiques finies à fabriquer, et chaque lentille semi-finie de l'ensemble comprend un composant holographique enregistré (13), les composants holographiques de l'ensemble présentant un nombre limité de configurations, et chaque configuration de composant holographique (Hi) est associé exclusivement à une courbe de base parmi les N courbes de base. L'invention concerne également un procédé de fabrication d'un ensemble de lentilles semi-finies et d'une lentille à partir d'une lentille semi-finie de l'ensemble.
