3e B31U Binocular Night Vision: The Professional Standard for Tactical Superiority in the Dark
In today's battlespace, night is no longer an obstacle but an ally for those who wield technology. The 3e B31U binocular night vision device is a high-tech Gen 3 system designed to provide maximum situational awareness. Unlike monoculars, the B31U dual-channel system provides the operator with stereoscopic vision, allowing them to accurately assess the distance and speed of objects, and confidently maneuver in difficult terrain.
Why is the 3e B31U the undisputed choice for combat missions?
The 3e B31U device combines lightweight design with exceptional durability. The use of 3rd generation image intensifier tubes (IITs) with green phosphorus ensures high contrast and detail even in critically low light conditions (starry sky, dense clouds).
- Stereoscopic perception: Two independent channels allow the brain to naturally process the image, which minimizes eye fatigue during long missions.
- Deployment speed: The device startup time is less than 3 seconds, which allows you to instantly respond to changing situations.
- Professional resolution: The 60-64 lp/mm indicator guarantees clear identification of targets at long distances.
- Reinforced housing: The use of special polycarbonate makes the device shock-resistant with minimal weight (up to 580 g).
Technical specifications (TTX) 3e B31U
The device is designed according to military standards, which is confirmed by its ability to operate in extreme temperatures and moisture protection according to the IP67 standard.

Intelligent Features for the Field
3e The B31U is equipped with a number of features to enhance operator safety and efficiency:
- Auto Power-Off (Flip-up): When the device is raised up (on the helmet), it automatically turns off, which saves the resource of the image intensifier and masks the glow of the eyepieces.
- Built-in IR illuminator: Indispensable for working with maps, servicing weapons or moving in conditions of complete absence of external light (caves, enclosed spaces).
- Alert system: Internal indicators of low battery and IR illuminator operation are always in the operator's field of view.
Autonomy and power supply
The device is adapted for long autonomous raids. The use of common AA batteries makes logistics as simple as possible:
- Standard mode: Up to 15 hours of operation on one AA battery.
- Extended mode: Up to 60 hours of continuous operation when using external battery pack with 4 AA batteries.
Applications and tactical flexibility
Thanks to its parameters, the 3e B31U is a universal tool:
- Driving equipment: The stereoscopic effect allows you to confidently drive vehicles and armored vehicles without using headlights.
- Assault operations (CQB): The minimum focusing distance (25 cm) allows you to operate effectively inside buildings.
- Night reconnaissance and surveillance: High resolution and contrast of green phosphorus help detect camouflaged targets against a background of vegetation.
Expert assessment: The 3e B31U is a "workhorse" of the modern soldier. It is not overloaded with unnecessary functions, but has everything you need: a reliable body, excellent 3rd generation optics and the ability to work for up to several days without replacing batteries.
Conclusion
Binocular night vision device 3e B31U - This is a reliable investment in the success of night operations. Its endurance, start-up speed, and image quality make it one of the best solutions in its class. By choosing the B31U, you choose confidence in every step in the dark.
Frequently Asked Questions about the 3e B31U Night Vision Binocular
Does this model support manual brightness control (Manual Gain)?
Yes, the model with the "U" index is specially designed to support the Manual Gain Control function. This allows the operator to manually adjust the image brightness, which significantly reduces eye fatigue during prolonged observation.
What power does the device use and how long does it last?
The device is powered by one standard AA battery. Battery life is approximately 15-20 hours. There is also a battery pack slot, which increases battery life to 50+ hours and serves as an excellent counterweight on the helmet.
Does the device have an automatic power-off function when tilted up?
Yes, the B31U has an Auto-off function. When you raise the binocular to a vertical position on the helmet, it automatically turns off. This prevents the operator from being unmasked and saves battery power.
How heavy is this binocular for constant wear?
This is one of the most compact and lightweight binoculars in its class. The body weight without the image intensifier is approximately 450-500 grams. Thanks to the center of gravity shifted towards the face,The strain on the neck is minimal even with long-term use.
What is the level of protection of the case from the external environment?
The device complies with the IP67 standard. This means it is completely dustproof and can withstand short-term immersion in water to a depth of up to 1 meter. It is designed for heavy rain, snow, and high humidity.
Which image intensifier tubes (IITs) can be installed?
The 3e B31U case is compatible with standard 18 mm image intensifier tubes of the MX-10160 or MX-11769 format. This allows the use of both Gen 2+ and top-end Gen 3 tubes with white or green phosphor.
