An optical system includes an optical assembly frame (140) having an input portion(102), an output portion (104), and an objective lens assembly (130) disposed at the input portion of the optical assembly frame. The objective lens assembly has an objective lens central optical axis (134). An eyepiece lens assembly (110) is disposed at the output portion of the frame. The eyepiece lens assembly has an eyepiece lens central optical axis (114) parallel to the objective lens central optical axis and offset from the objective lens central optical axis by a distance. An inverting image intensifier (120) is disposed between the objective lens assembly and the eyepiece lens assembly. The image intensifier has an image intensifier optical axis (124) parallel to the objective lens central optical axis and parallel to the eyepiece lens central optical axis. The image intensifier optical axis is offset from both the objective lens central optical axis and the eyepiece lens central optical axis by about half the distance.

L'invention concerne un système optique qui comprend un bâti d'ensemble optique (140) comprenant une partie d'entrée (102), une partie de sortie (104), et un ensemble lentille de focalisation (130) placé au niveau de la partie d'entrée du bâti d'ensemble optique. L'ensemble lentille de focalisation comporte un axe optique central de lentille de focalisation (134). Un ensemble lentille oculaire (110) est placé au niveau de la partie de sortie du bâti. L'ensemble lentille oculaire comporte un axe optique central de lentille oculaire (114) parallèle à l'axe optique central de lentille de focalisation et décalé par rapport à l'axe optique central de lentille de focalisation d'une certaine distance. Un intensificateur d'image inversée (120) est placé entre l'ensemble lentille de focalisation et l'ensemble lentille oculaire. L'axe optique (124) de l'intensificateur d'image est parallèle à l'axe optique central de lentille de focalisation et parallèle l'axe optique central de lentille oculaire. L'axe optique de l'intensificateur d'image est décalé par rapport à l'axe optique central de la lentille de focalisation et à l'axe optique central de la lentille oculaire d'environ la moitié de la distance.
