Abstract

Une lentille monolithique à double gradient axial (30) est décrite; la lentille possède un axe optique et trois sections perpendiculaires à celui-ci: une première section (34) ayant un premier profile dégradé d'indice de réfraction et ayant une surface extérieure, une section médiane (32) ayant un deuxième profile dégradé d'indice de réfraction, et une troisième section (36) ayant un troisième profile dégradé d'indice de réfraction et ayant une surface extérieure. Un gradient de l'indice de réfraction est prévu au moins dans la première et troisième section. Par suite de la sélection appropriée des gradients, les abberrations sphériques et chromatiques sont éliminées ou au moins réduites, et la dépendance thermique des caractéristiques optiques est réduite au minimum.
