Abstract

La présente invention concerne une lentille à deux composants du type rotatif ou du type puzzle pour un dispositif de communication portable personnel ou un appareil photographique de dispositif électronique. Un indice de réfraction optique d'une lentille dure est utilisé en tant que procédé pour utiliser un appareil photographique reflex mono-objectif numérique (DSLR) ou une lentille d'appareil photographique incorporée dans un dispositif portable, et un état de correction d'aberration est ajusté et un angle de vue est corrigé selon une valeur F d'une mémoire CMOS ou d'un CCD de l'appareil photographique de telle sorte que la lentille à deux composants est apte à fonctionner en tant que macro-objectif, en tant qu'œil de poisson et en tant que téléobjectif. La lentille peut être attachée et détachée de manière aisée de façon à améliorer l'aptitude à l'assemblage et les performances de prise de vue d'une lentille optique du dispositif portable.
