BNVD1431 Elbit PH White Phosphor Gen 3+: The Technological Peak of Night Vision (FOM 2591)
In modern combat, the night belongs to those with the best technology. The BNVD1431 night vision binocular with Elbit PH Gen 3+ tubes is an uncompromising device that provides the operator with previously unattainable clarity and detail. The combination of premium American-made image intensifier tubes and a reliable articulating body makes this binocular the choice of professionals for whom situational awareness in complete darkness is a matter of survival and mission success.
Why are the Elbit PH Gen 3+ performance game-changers?
At the heart of the device are the Elbit Systems (USA) MX-10160 image intensifier tubes. Thanks to white phosphorus (P45) and innovative manufacturing methods, these tubes demonstrate performance that significantly exceeds standard military requirements (Mil-Spec).
- FOM 2591+: Figure of Merit indicating extreme resolution and image clarity.
- SNR 34 (Signal-to-Noise Ratio): Minimum level of “noise” on the image even in critically low light conditions (Overcast Starlight).
- Auto-Gating: A system of automatic voltage regulation on the photocathode, allowing operation in conditions of dynamic lighting changes (flashes, shots, backlighting) without the risk of damaging the image intensifier and blinding the operator.
- Resolution 76 lp/mm: Ensures identification of targets at distances where conventional night vision devices see only blurred silhouettes.
Technical specifications (TTX) BNVD1431 / Elbit PH
This configuration combines lightness (only 500 g) and phenomenal light sensitivity, which makes the device ideal for long foot raids and driving vehicles.

BNVD-1431 housing ergonomics: Flexibility and reliability
The BNVD-1431 housing is a modern interpretation of the legendary PVS-31, but with the ability to use standard PVS-14 optics. The main advantage is the articulating design, which allows you to fold down each channel separately. This is critical for:
- Using a collimator sight or thermal imager with the naked eye.
- Quickly adapting to sudden changes in lighting.
- Reducing the operator's profile when raising the device to the helmet.
Operational benefits of use
- White phosphorus (P45): Provides a black and white image that the human eye perceives more naturally. This reduces brain and eye fatigue during multi-hour missions.
- Deep perception (Stereoscopic effect): Unlike monoculars, a binocular allows you to accurately assess the distance and speed of objects, which is necessary for driving a car or close-quarters combat (CQB).
- Energy efficiency: The device operates on one CR123A battery, and the presence of a connector for an external battery pack allows you to increase the operating time to several days.
- Universal mount: Compatibility with Dovetail standards ensures reliable fixation on the most popular helmet systems (Wilcox, Norotos).
Expert opinion: FOM above 2500 in combination with low EBI (0.61) makes this device ideal for working in conditions of "zero" visibility, for example, in dense forests or enclosed spaces without external light sources.
