Title (EN) LENS MANUFACTURING METHOD AND MOLDING DIE
(FR) PROCÉDÉ DE FABRICATION D'UNE LENTILLE ET MATRICE DE MOULAGE
(JA) レンズの製造方法及び成形金型
Abstract: front page image
(EN)Provided are a lens manufacturing method and a molding die for which an adjustment operation for astigmatic aberration is easy, and which is capable of suppressing occurrence of comatic aberration accompanying the adjustment. By rotating a fixed-side transfer plane (second transfer plane) (61c) around an axis while fixing a movable side transfer plane (first transfer plane) (51c), astigmatic aberration of a lens (10) is adjusted, and therefore, adjustment operation for the astigmatic aberration is simplified. Furthermore, in adjusting the astigmatic aberration, the operation can be performed while the movable side transfer plane (first transfer plane) (51c) is fixed, and therefore, it is possible to relatively reliably suppress occurrence of comatic aberration accompanying the adjustment.
(FR)L'invention concerne un procédé de fabrication de lentille et une matrice de moulage pour lesquels une opération de correction de la déviation astigmatique est facile et qui sont capables de supprimer l'occurrence présentant une aberration de coma accompagnant la correction. Par rotation d'un plan de transfert latéral fixe (second plan de transfert) (61c) autour d'un axe tout en fixant un plan de transfert latéral mobile (premier plan de transfert) (51c), aberration astigmatique d'une lentille (10) est corrigé, et par conséquent, simplifie l'intervention de correction de l'aberration astigmatique. De plus, la correction de l'aberration astigmatique peut être effectuée tandis que le côté mobile du plan de transfert (premier plan de transfert) (51c) est fixé, et par conséquent, il est possible de supprimer de manière fiable l'occurrence d'aberration comatique accompagnant le réglage.
(JA) アス収差の調整作業が容易であり、調整に伴ってコマ収差が発生することを抑制できるレンズの製造方法及び成形金型を提供する。可動側転写面(第1転写面)51cを固定したままで固定側転写面(第2転写面)61cを軸のまわりに回転させることによりレンズ10のアス収差を調整するので、アス収差の調整作業が簡略化される。また、アス収差の調整に際して可動側転写面(第1転写面)51cを固定したままとできるので、調整に伴ってコマ収差が発生することを比較的確実に抑制できる。
