What this unit is meant for
This goggle is made to let you move, observe, and track while your hands remain free, so you can focus on the mission rather than the optics. You’ll be able to use it for navigation, observation, vehicle tracking, and any task where maintaining both mobility and visual acuity in darkness matters.
Key features
You should know the main selling points before you commit, and the BNVD-51 has a number of them that stand out. It pairs Gen 3 Pinnacle image intensifier tubes with a Ghost White phosphor output, offering a unique visual appearance and improved clarity for many users.
Ghost White Phosphor image tubes
The Pinnacle tubes output a white phosphor image instead of the traditional green, which changes contrast perception and often improves object recognition. You’ll notice reduced eye strain and clearer detail on many surfaces because the white phosphor tends to render a more natural-looking image for many users.
True dual-channel binocular design
The BNVD-51 uses a dual-channel optical path so you’re getting stereoscopic vision, which preserves depth perception and improves tracking of moving targets. You’ll appreciate how depth cues remain intact, making it easier to judge distances and move quickly in dim conditions.
Built-in infrared (IR) illuminator
A built-in IR illuminator lets you add active illumination when ambient light is insufficient for passive night vision. You’ll be able to see in complete darkness when you activate the illuminator, which is helpful for confined or extremely dark environments.
51-degree field of view (FOV)
The 51° FOV broadens situational awareness compared to narrower optics, which helps when you need to scan areas or maintain peripheral awareness. You’ll find it less tunnel-like than many monoculars or small goggles, so you can react faster to threats or points of interest appearing at the edges of your vision.
Rugged, fog- and water-resistant housing
Armasight encases the BNVD-51 in a tough, compact housing designed to resist fogging and light to moderate moisture. You’ll be able to operate in adverse weather with confidence, though you should still follow the manufacturer’s guidelines for immersion and cleaning.
Articulating design and monocular option
The BNVD-51 articulates so you can swing it up and out of your way or configure it as a monocular over either eye. You’ll preserve your natural night vision in the unused eye when you opt for monocular operation, which is handy if you need unaugmented vision for certain tasks.
Manual gain control and automatic protection
Manual gain lets you set the image brightness to your preference, while the automatic protective system shuts down the image intensifier tubes if ambient light becomes too strong. You’ll appreciate the combination because it permits customization during low light but still protects the tubes from sudden bright-light exposure.
