Abstract

Un module de lentille (100), un système de panoramique-inclinaison (201) et un véhicule aérien sans pilote (1000). Le module de lentille (100) comprend un support de lentille (10), un barillet de lentille (20) et un joint d'étanchéité (30). Le barillet de lentille (20) est monté amovible sur le support de lentille (10). Le joint d'étanchéité (30) est ajusté par encliquetage dans l'un quelconque du barillet de lentille (20) et du support de lentille (10), et est situé au niveau d'une articulation du barillet de lentille (20) et le support de lentille (10) de façon à sceller un espace entre le barillet de lentille (20) et le support de lentille (10).
