SECTION 1. INTRODUCTION
1.1 BINOCULARS
This manual covers the BNVD night vision binoculars and all applicable
components. It is recommended that you read and understand this
manual to optimize the binoculars operation.
1.2 INTRODUCTION
The BNVD is a hand-held, head-mounted or helmet-mounted night
vision system that enables mobility, driving, weapon firing, short-range
surveillance, map reading, vehicle maintenance and administering first
aid during operation in both moonlight and starlight.
The BNVD is a dual-channel night vision device. The BNVD uses
advanced, multi-coated optics and a tough, compact, and ergonomic
composite housing. The BNVD can be used as a monocular or binocular
goggles, or stowed out of the way without removing. Rotating binocular
design allows low profile against helmet when in stowed position. This
device operates with a single gain control knob and utilizes features
like a flip up turn off with flip down turn back on function, when used
in conjunction with a compatible head/ helmet mount. There is also an
integral infrared illuminator for reading a map.
1.3 FEATURES
• Rotating binocular design allows low profile against helmet when in
stowed position and ability to use as a single monocular
• Binocular design for sustained viewing periods and improved depth
perception
• Manual system gain and focus adjustments for custom image quality
optimization
• Auto OFF when stowed; resumes power when deployed
• Integrated infrared (IR) illuminator
• Head or helmet-mountable
• Low-battery, bright light cut-off, and IR indicators in eyepiece
• Self-contained system operating on a single AA or CR123 battery
• Compact and lightweight, rugged construction
• Optional remote battery pack for extended use
• Limited 2-year warranty

1.5 IMAGE INTENSIFIED NIGHT VISION
VERSUS INFRARED THERMAL VISION
Image Intensification “I
2
” works by collecting tiny amounts of light,
including the lower portion of the infrared light spectrum, that are
present but may be imperceptible to our eyes, and amplifying it to the
point that we can easily observe the image.
Thermal imaging technology operates by capturing the upper portion of
the infrared light spectrum, which is emitted as heat by objects instead
of simply reflected as light. Hotter objects, such as warm bodies, emit
more of this light than cooler objects, like trees or buildings.
The thermal vision device makes images from heat, not light, a feat
impossible for the naked eye or image intensified (I
2
) night vision
devices. This allows you to see clearly without any visible light. People,
animals, and objects all generate or reflect heat, and are clearly seen
by the thermal vision device, in even the most adverse conditions.
Thermal is best used to detect the desired object. It is the best 24-hour
imaging option.
Night vision devices provide a more natural image, wider field of view
(FOV), wider operating temperature, and longer battery life.
