Robust, lightweight and functional – Developed for professional use

The glass-fibre-reinforced housing of the NT1431 A3 guarantees high durability at a weight of under 500 g (without battery). This makes the device suitable for long operations where comfort and reliability are decisive.

• Sturdy, impact-resistant housing with low weight
• Ergonomic design for extended wear
• Manual Gain-Control for individual brightness adjustment
• Auto-Gating technology for optimal adaptation to changing light conditions

Optical precision – High-quality components to US MIL-SPEC

The NT1431 A3 is equipped with original US MIL-SPEC eyepieces and objective lenses. These deliver a distortion-free image with high edge sharpness – essential for precise observation at night.

• Crystal-clear image reproduction even in low light
• No “Fisheye” effect or image curvature
• Dioptre adjustment from +2 to -6 for individual visual acuity
• Focus range from 25 cm to infinity

Powerful Photonis tubes – A selection for every requirement profile

Various Generation 2+ tubes from the Photonis range are available for the NT1431 A3:

• Photonis 4G+ – high-end tube with maximum light amplification
• Photonis Delta & Commercial – strong performance for versatile operations
• Excellent low-light amplification and image stability
• Calm, detailed image even in extremely poor lighting conditions

---

Expandable power supply for maximum operating time

Power is supplied as standard by one AA battery with up to 16 hours of run time. With the optional external Battery Pack (4x AA), the operating time can be extended to up to 60 hours. The Battery Pack is also equipped with a 360° IR flashing light for signalling.

• Internal and external power supply options
• Tool-free battery change
• Long operating time without recharging

---

Flexible binocular design for situational use

Thanks to the rotatable binocular design, each monocular can be swivelled or flipped up individually. This offers the user maximum flexibility and adaptability – for example for asymmetric use or a temporary switch to one eye.

• Rotatable monoculars for individual adjustment
• Can be flipped up individually for combined use with the naked eye
• Integrated sensor-controlled Flip-Up Shut-Off to prevent unintentional self-illumination

---

Areas of application and expansion options

The NT1431 A3 is ideally suited for:

• Tactical operations and use by government and law enforcement agencies
• Security services and close protection
• Hunters and outdoor activities at night

With accessories such as the Fused Clip-On thermal imaging module, the device can be expanded into a powerful fusion night vision solution – for combined imaging with IR and image intensification.
