Abstract[English]
A periscope-type optical system with a shortened total length of optics is disclosed. The optical system includes a reflective optical element (P) for bending an optical path by 90 degrees from an object side toward an image side and a rear group of lenses (G_rear) on the optical path following the reflective optical element (P), wherein the rear group of lenses (G_rear) has a positive refractive power as a whole. The reflective optical element (P) has a convex curvature on a first surface (S1) of the object side and a concave curvature on a third surface (S3) of the image side.[French]
Un système optique de type périscope ayant une longueur totale raccourcie d'optique est divulgué. Le système optique comprend un élément optique réfléchissant (P) pour courber un trajet optique de 90 degrés depuis un côté objet vers un côté image et un groupe arrière de lentilles (G_rear) sur le trajet optique suivant l'élément optique réfléchissant (P), le groupe arrière de lentilles (G_rear) ayant une réfringence positive dans son ensemble. L'élément optique réfléchissant (P) présente une courbure convexe sur une première surface (S1) du côté objet et une courbure concave sur une troisième surface (S3) du côté image.
