L'objectif périscopique comprend un premier groupe de lentilles, un deuxième groupe de lentilles, et un cône de lentille avec lequel un ensemble photosensible et un ensemble de rotation de lumière sont assemblés dans un module de caméra périscopique. La dimension radiale du deuxième groupe de lentilles est plus petite que la dimension radiale du premier groupe de lentilles. Le cône de lentille comporte un canal optique, et le canal optique est adapté pour correspondre à un trajet photosensible de l'ensemble photosensible. Le premier groupe de lentilles et le deuxième groupe de lentilles sont disposés coaxialement dans le canal optique du cône de lentille, le premier groupe de lentilles étant exposé au cône de lentille dans une direction de hauteur du cône de lentille.
