Abstract

La présente invention concerne un procédé de fabrication d'un objectif (11) qui comprend un corps de base (12) transparent et des éléments optiques de formation d'image (3a-h) qui sont disposés le long d'un axe optique (OA) replié. L'angle α entre des sections de l'axe optique (OA1-OA9) avant et après le pli est inférieur à 180°. Les éléments optiques de formation d'image (éléments 3a-h) comprennent des éléments réfléchissants dont au moins un présente une surface réfléchissante incurvée sans symétrie de révolution. Le procédé de fabrication comprend la réalisation d'un corps de base (12) transparent ainsi que la formation des éléments optiques de formation d'image (éléments 3a-h) dans le corps de base (12). L'invention concerne en outre un procédé de fabrication d'un appareil de prise de vues (10), un objectif (11) et un appareil de prise de vues (10).
