ABSTRACT:
An ANVIS 6 type of binocular night vision device includes a pair of night vision monocular scopes which adjustably depend from a support frame in front of a user's eyes. The support frame includes an interpupillary distance adjustment mechanism which allows placement of the monocular scopes to better achieve binocular vision with depth perception. The image quality of binocular vision afforded by the device is improved and made more durable by providing the monocular scope mounts with a dirt-shedding dry threaded engagement with their respective interpupillary adjustment shafts, as well as providing a laterally extended threaded engagement of these mounts with the adjustment shafts. As a result, wobble of the monocular scope mounts relative to the frame is significantly reduced, and wear of the component parts which over time contributes to increased wobble is also reduced.
