Abstract[English]
A switching zoom lens comprises, from an object side to an image side along an optical axis (OA), a reflective optical element (P) to bend an optical path from the object side to the image side, a front lens group (Gf) with a positive refractive power, and a rear lens group (Gr) comprising three or more and five or less lens elements (L7-L10). When zooming from a wide angle end to a telephoto end, the rear lens group (Gr) is inserted between the front lens group (Gf) and an imaging surface (IMG), and when zooming from the telephoto end to the wide angle end, the rear lens group (Gr) is moved out of the optical path of the switching zoom lens.[French]
L'invention concerne une lentille de zoom à commutation comprenant, d'un côté objet à un côté image le long d'un axe optique (OA), un élément optique réfléchissant (P) pour courber un trajet optique à partir du côté objet vers le côté image, un groupe de lentilles avant (Gf) ayant une réfringence positive, et un groupe de lentilles arrière (Gr) comprenant trois ou plus et cinq ou moins éléments de lentille (L7-L10). Lors d'un zoom d'une extrémité grand angle à une extrémité téléobjectif, le groupe de lentilles arrière (Gr) est inséré entre le groupe de lentilles avant (Gf) et une surface d'imagerie (IMG), et lors d'un zoom de l'extrémité téléobjectif à l'extrémité grand angle, le groupe de lentilles arrière (Gr) est déplacé hors du trajet optique de la lentille de zoom à commutation.
