L3Harris BNVD-1531

The L3 BNVD-1531 is the result of the L3Harris focus on continuous product improvements in the areas of size, weight, performance and power consumption. The 1531 offers a lightweight, ergonomic design similar to the AN/PVS-31 but with significant weight reduction over the AN/PVS-15. It also incorporates features such as adjustable diopters, manual gain adjustment, individually rotating monoculars and an integrated infrared illuminator. The 1531 can be operated as a helmet-mounted or handheld system.

The two main differences between the BNVD-1531 and the PVS-31a is the integrated IR illuminator and adjustable diopters.  The BNVD-1531 uses standard milspec PVS-14 optics which gives the user focusable diopters, but also, allows for a more cost effective solution.

The BNVD-1531 can be run both off of an onboard AA battery or powered from the included PVS-31 battery pack. Because of the light weight design, the user does not need to run a counterweight and can simply use the battery pack to balance the helmet. The PVS-31 battery pack also has an on board IR strobe for signaling and aerial identification.  The IR strobe is operated by a single switch on the back of the battery pack.  One great thing about the ability to run a battery pack is the speed in which the goggles can be up and running. With the PVS-31 the user simply can drop the dovetail on a Wilcox G24 mount and plug in the battery cable to the battery pack port on the BNVD-1531 housing and use their goggles.

The L3Harris BNVD-1531 has an articulating housing with independently rotating optical pods.  This lets the user deploy both tubes or a single tube.  This is especially helpful when users are deploying their BNVD-1531’s while using a thermal device.  The optical pod articulation also lets users stow their goggles without having to flip the goggles up on the helmet mount.  This reduces snag hazard and additional height added to the helmet.

Tube Specs

The BNVD-1531 uses L3 Filmless White Phosphor autogated image intensifier tubes with a 2376 min FOM rating from the factory.  These filmless tubes provide incredible clarity, low light and high light performance, and increased depth perception.  These are L3’s most advanced intensifier tubes and offers significant performance increases over other white phosphor systems.

2376 minimum FOM Unfilmed White Phosphor:

• FOM: 2,376  minimum
• Milspec Spot Spec: can have max 4 spots per tube larger than .003″, no spots larger than .003″ in zone 1.  Spots </= .003″ are acceptable.
