It features a 3rd-generation autogain brightness-controlled image intensifier tube and a compact structure, making it suitable for various applications.
It can be worn on the head or handheld, and each eyepiece can independently flip up to 140° for rapid switching between combat modes under different lighting conditions, ensuring adaptability to any harsh operational environment.
The unique built-in body posture system automatically adjusts settings based on the user's current state. Once the night vision device is flipped up onto the helmet and not in use, it powers off automatically to reduce stray light emission from eyepieces, avoiding target exposure.
The ZX-NV31C automatically adjusts image brightness to adapt to different combat lighting conditions, enhancing nighttime operational capabilities.
