(EN) DEVICE AND METHOD TO PROVIDE DIFFERENT OPTICAL MAGNIFICATIONS
(FR) DISPOSITIF ET PROCÉDÉ POUR FOURNIR DIFFÉRENTS GROSSISSEMENTS OPTIQUES
Abstract
(EN) Viewing apparati and methods. In one example, the viewing apparatus comprises a first objective lens having a first focal length; a second objective lens having a second focal length; and a common eyepiece lens having a third focal length; wherein the viewing apparatus is configured, in a first viewing mode, that such an image viewable through the common eyepiece lens comprises, in different parts thereof, respective portions of respective fields of view, FOV, through the first objective lens and through the second objective lens with different magnifications.
(FR) L'invention concerne des appareils et des procédés de visualisation. Dans un exemple, l'appareil de visualisation comprend: une première lentille d'objectif ayant une première longueur focale; une seconde lentille d'objectif ayant une seconde longueur focale; et une lentille oculaire commune ayant une troisième longueur focale; l'appareil de visualisation est configuré, dans un premier mode de visualisation, de telle sorte qu'une telle image visible à travers la lentille oculaire commune comprend, dans différentes parties de celle-ci, des parties respectives de champs de vision respectifs, FOV, à travers la première lentille d'objectif et à travers la seconde lentille d'objectif avec différents grossissements.
