L3Harris AN/PVS-31A BNVD

PLEASE INQUIRE FOR STOCK STATUS BEFORE PLACING YOUR ORDER

The L3Harris AN/PVS-31A has been in use by U.S. Special Forces as well as other allied militaries for several years now, but they have not been widely available to the commercial market.  They are one of the most sought after and requested night vision devices produced today and are now commercially available.  These are not contract overruns, but rather brand-new, factory systems.

The AN/PVS-31A was designed to replace the legacy AN/PVS-15 BNVD in the US SOCOM inventory.  It is the smallest and lightest weight system on the market at just under one pound, and nearly as light as a single monocular.  While working with the input from US SOCOM, the AN/PVS-31A was designed to increase system resolution, significantly reduce neck strain, improve center of gravity and provide overall improved operational utility for today’s war fighters.

The AN/PVS-31A features a dual articulating design which allows users to operate the unit with either one or both eyes.  This is useful when operating a thermal optic or other passive aiming device while maintaining night vision on one side only.  This feature also allows the user to stow the pods comfortably against the helmet for a lower profile while in a vehicle or where head space may be limited.  Individual pods are powered off when articulated to eliminate backsplash and protect the image intensifier tubes.

The AN/PVS-31A is comprised of a simple, minimalist design, but while maintaining key operational features.  A single rotary control activates the unit, as well as provides gain control.  It can be operated while wearing gloves and without being able to see the controls.  This unit does not include an onboard IR illuminator to save weight as well as most US SOCOM Operators already utilize weapon mounted IR laser sights and other illumination devices.

Housing and Optics Information

The L3Harris AN/PVS-31A is constructed using ultralight, yet high-strength reinforced polymer construction to create one the lightest weight but highest performing binocular night vision devices (BNVD) currently on the market.  It exceeds MIL-STD-810G and US SOCOM test protocols for drop and impact resistance by a factor of two.  Power is supplied by a single onboard AA battery, but can also be powered externally using the included battery pack and cable.  The external battery pack is powered by four AA batteries and can also serve as a counterweight when mounted to the rear of the helmet.  Additionally the external power pack features built-in dual IR strobes for ground personnel identification and situational awareness between operators.  This system will operate for at least eight hours on a single AA and at least 25 hours using the external battery pack.

The AN/PVS-31A utilizes the highest quality optics available.  Fixed diopters are standard and set at -0.50, which are optimized for the 95th percentile of users.  This eliminates the need for diopter adjustment and allows for faster setup.  For the small percentage of users who require custom diopters, they may be special ordered.  A durable aluminum dovetail mounting interface provides secure attachment to the user’s choice of helmet mount.  Only the highest quality optics are used for these units.

All units are factory assembled by L3Harris, nitrogen-purged, and thoroughly tested.

Image Intensifier Tube Information

The L3Harris AN/PVS-31A utilizes the following image intensifier tube option:

• L3Harris Unfilmed White Phosphor, 2376+ FOM

All image intensifiers used in these units are “Grade-A”, meaning they have the most stringent spot (blemish) tolerances. 

L-3 Harris filmless image intensifier tubes perform well in all conditions, but especially in rural or very dark environments.  Typically filmless tubes will have higher average performance specifications on their data sheets than comparable thin-film tubes, and produce an excellent image.

Warranty Information

The L3Harris AN/PVS-31A is built to extremely rugged specifications and designed to last a long time under harsh professional use.  These units carry a one year factory warranty, and may continue to be serviced by L3Harris for the life of the unit beyond the warranty period, so buy with confidence that you will be enjoying this unit for years to come.
