AN/AVS-9
The AN/AVS-9 the JETDS designation for a binocular night vision device developed for and used by aviators in the U.S. military.
Overview
The housing is compatible with MX-10160 format image intensifier tubes.
The AN/AVS-9 uses the ball detent mounting system. It features no onboard power supply or on/off switch, and instead relies on the connected mount to supply the power through the contacts under the "ball" of the mount.
The four protrusions on each of the objective lenses are intended to allow the user to quickly adjust the focus.
The housing features adjustible interpupillary distance, distance from the eye, and pitch.
Except for one difference, the ocular assemblies are almost identical and in fact compatible with AN/PVS-14 ocular assemblies. The only difference is an absence of the threading for eyecups, sacrificial lenses or filters.
In contrast, the objective lenses have a different threading than the AN/PVS-14 counterparts, with lenses and housings referred to as ANVIS-threaded.
