Nora NVG-14 Single-Tube Monocular Night Vision Device for Tactical, Hunting, and Low-Light Outdoor Observation
-
Nora NVG-14 multi-functional monocular low-light night vision device is developed based on advanced photoelectric technology and features a newly designed optical system with a 50° field of view, providing a wider observation range and a more stable low-light visual experience.
The device is equipped with a large eyepiece aperture and an extended eye relief distance, significantly improving viewing comfort and image stability. It delivers high-resolution, finely detailed imaging while combining a wide field of view with a lightweight design. The unit is compact, lightweight, and suitable for long-duration wear and use.
The operation interface is simple and intuitive, offering a high cost-performance advantage. It also supports the use of a magnifier lens to flexibly adjust magnification, meeting different operational requirements in various scenarios.
Built-in infrared auxiliary illumination allows clear visibility in complete darkness, while an automatic bright light protection system effectively prevents damage to the image intensifier tube, improving device safety and service life.
This product has a wide range of applications in fully unlit nighttime environments, including outdoor hunting, wilderness exploration, anti-theft patrols, maritime operations, and night-time engineering work. It is an ideal optical device for professional night observation and outdoor activities.
