Abstract

L'invention porte sur une lentille optique (10) comprenant une première lentille optique (111), une second partie de lentille (12) et un élément de protection contre la lumière (13). La seconde partie de lentille (12) comprend un barillet de lentille (121) et au moins une seconde lentille optique (122) montée dans le barillet de lentille (121). La première lentille optique (111) est disposée sur la seconde partie de lentille (12). L'élément d'ombrage de lumière (13) est suspendu et supporté au-dessus de la première lentille optique (111) et il recouvre une surface latérale de la première lentille optique (111) et au moins une partie d'une surface supérieure de celle-ci. L'élément d'ombrage de lumière (13) et la première lentille optique (111) sont configurés indépendamment l'un de l'autre en termes de structure, ce qui peut réduire l'impact du changement d'état de l'élément d'ombrage de lumière (13) sur l'état de la première lentille optique (111). La présente invention concerne également un module de caméra (100) comprenant la lentille optique (10) et un procédé d'assemblage de la lentille optique (10).
