The AN/AVS-9 the JETDS designation for the F4949 binocular night vision device developed by Elbit Systems of America for 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 housing features adjustible interpupillary distance, distance from the eye, and pitch.

Lenses

AN/PVS-14 vs. AN/AVS-9 ocular assemblies
Comparison between AN/PVS-14 and AN/AVS-9 ocular assemblies.

Except for one difference, the ocular lens 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.

Housings with this combination of lens threadings as well as the objective lenses are usually referred to as ANVIS-threaded. Other ANVIS-threaded housings include the AN/AVS-6, AN/PVS-23 and the Fenn NG700D, for example.

The four protrusions on each of the objective lenses are intended to allow the user to quickly adjust the focus.
