NT1431 A3 – State-of-the-art binocular night vision device with high-performance Photonis tubes

The NT1431 A3 is a state-of-the-art binocular night vision device that sets new standards in terms of ruggedness, functionality, and cost-effectiveness. It was developed specifically for demanding applications and features a lightweight yet durable housing that guarantees a long service life. Equipped with cutting-edge technology, the device is suitable for both professional and private users.

Key Features & Benefits

Integrated IR Illuminator: A built-in short-range infrared illuminator enhances visibility in complete darkness, e.g., when navigating indoors or reading maps.

Flip-Up Shut-Off Function: When the device is flipped up, the power is automatically shut off—this function can be temporarily or permanently disabled by the user.

Optimized Stability & Functionality: The NT1431 A3 offers an improved auto-gating function for optimal adaptation to changing light conditions. An integrated manual gain function allows for manual brightness control.

Lightweight & Durable: The glass-fiber-reinforced housing combines outstanding stability with low weight. Weighing less than 500 g, the device is ideal for extended wear.

High-Quality MIL-SPEC Optics: Equipped with genuine U.S. MIL-SPEC eyepieces and lenses for maximum image sharpness all the way to the edges without distortion.

Expandable power supply: A single AA battery provides up to 16 hours of operation. With an external battery pack (including a 360° IR strobe light), up to 60 hours of operation are possible.

Flexible binocular-rotating design: The monoculars can be individually swiveled and folded up as needed.

Wide Range of Tube Options: Available with Photonis Echo, Echo14+, Echo+, 4G, and 4G+ tubes. The Echo14+ is a tube specifically optimized for the NT1431 and offers an attractively priced option with good performance, though it has a slightly higher error tolerance compared to the Echo+.

Latest Photonis technology: The carefully selected tubes ensure excellent contrast, low noise, and high light amplification even under the most challenging conditions.
