A night vision attachment (NSV) mountable on a firearm and intended for a sighting telescope (ZF), comprising an objective (1) of the night vision attachment, a low-light- level amplifier (2), an optical assembly (3) and an eyepiece (4) of the night vision attachment, is formed in such a way that a beam offset between radiation entering through the objective (1) of the night vision attachment and emerging through the eyepiece (4) of the night vision attachment is achieved by means of the optical assembly. The offset takes place from the optical axis (Al) of the objective (1) of the night vision attachment on to the optical axis (A2) of the eyepiece (4) of the night vision attachment, the latter corresponding substantially to the optical axis (A2) of the sighting telescope (ZF) downstream of the attachment. Consequently, night vision attachment (NSV) and sighting telescope (ZF) can be mounted as close as possible to the housing of the firearm.

La présente invention concerne un accessoire de vision nocturne (NSV) montable sur une arme à feu et destiné à une lunette de visée (ZF), comprenant un objectif (1) dudit accessoire, un amplificateur de niveau de faible éclairage (2), un ensemble optique (3) et un oculaire de visée (4) dudit accessoire, qui est formé de telle manière à ce qu'un décalage de faisceau entre le rayonnement pénétrant à travers l'objectif (1) de l'accessoire de vision nocturne et ressortant à travers l'oculaire de visée (4) dudit accessoire soit obtenu au moyen de l'ensemble optique. Le décalage se produit à partir de l'axe optique (Al) de l'objectif (1) de l'accessoire de vision nocturne vers l'axe optique (A2) de l'oculaire de visée (4) de ce même accessoire, le second correspondant pratiquement à l'axe optique (A2) de la lunette de visée (ZF) en aval de l'accessoire. Par conséquent, l'accessoire de vision nocturne (NSV) et la lunette de visée (ZF) peuvent être montés le plus près possible du boîtier de l'arme à feu.
