Product description

Go on your next mission with the FLIR BNVD-51 3AG 3rd-Generation Dual-Tube Night Vision Binocular. The device detects (invisible to the naked eye) near-infrared images of your surroundings, people, and objects. Its images have a high enough resolution to allow identification of individuals and fine artifacts at considerable distances. To provide this penetrating night vision capability, FLIR outfitted the device with two thin film auto-gated 3rd-generation image intensifier tubes (IITs) (one for each optical path) that generate high-resolution green images. This dual-tube (binocular) configuration also provides better perception of depth, which can be a valuable asset in quickly changing hunting or tactical situations.

This version of night vision technology offers users a manual gain control for adjusting image brightness and contrast, a bright light cutoff function for preventing tube overload and burnout, and an automatic-off function for saving battery power when not in use. Another highlight of this device is its auto-gating of the power supply, which provides the intensifier tube with some immunity to bright-light exposure, prevents burnout, and improves tube life. The multi-coated 1x optical system offers a generous 51° field of view, a diopter adjustment, and an interpupillary adjustment. In addition to viewing distant targets, the opto-mechanics allow you to focus as close as 0.8' away, which is helpful for reading maps or instructions without stowing away the binocular. To improve the effectiveness of close-range visibility in very low light, this night vision device also has a built-in infrared LED illuminator with a fixed flood lens. With the help of internal electronics and in-view indicators, you can monitor the battery life and status of the infrared illuminator.

To accompany you on your missions and adventures, the binocular is outfitted with a strong, lightweight, and water-resistant composite body. It is also slip-free, thanks to an ergonomic design. For comfort and ease of adjustments, the focusing and diopter rings are heavily knurled. The device is ready to use out of the box, as it ships with a battery and two headgear mounting adapters. Also included are two demist shields and two sacrificial windows to protect the external lenses from damage, and a soft carrying case for storage and transport.
