Abstract: 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 (A1) 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.
