Abstract

Appareil de prise de vues compact, rigide, possédant un trajet optique brisé entre un objectif et un plan de film. Il comprend un prisme possédant une surface d'entrée, une surface de sortie recouvrant le plan de film et en étant faiblement écartée et une surface réfléchissante. La surface de sortie à la fois réfléchit la lumière entrant dans le prisme à la surface d'entrée et transmet la lumière hors du prisme. La surface réfléchissante est inclinée pour renvoyer vers la surface de sortie, et la transmettre vers le plan de film, la lumière réfléchie intérieurement sur la surface de sortie. La surface d'entrée du prisme est inclinée par rapport à la surface réfléchissante/ transmettrice d'un angle plus grand que l'inclinaison relative de la surface réfléchissante. Application, notamment, à la photographie instantanée.
