US NightVision USNV-321G 1x 3rd Generation Night Vision Binocular

Utilizing ITT Industries' 3rd generation image intensifier tubes, the US Night Vision USNV-321G is a night vision goggles unit offering true stereoscopic night vision capability(dual objective lenses, intensifier tubes and eyepieces) in a lightweight, ergonomic design that is easily managed.  The USNV-321G has built-in bright source protection circuitry safeguarding the unit in the event of accidental exposure to bright light sources, as well as automatic brightness and light gain control to mate the values appropriately to the scene.  The USNV-321G also includes an integral infrared light source, providing longrange illumination in total darkness(such as in an enclosed room).  As it arrives it is a 1x unit, but can quickly be changed into a night vision binocular with the addition of two optional 3x military lenses.

PLEASE NOTE:  There are many variables which influence the distance one sees with night vision devices-amongst them the object's size, the level of detail being sought and the observation conditions.  Night vision devices detect much further under a full moon and clear skies than they will under a new moon and cloudy skies.  Many different formulas are used to determine the statistic of maximum viewing range and this varies by manufacturer, so ultimately the generation of the intensifier tube is much more relevant than any quoted statistic when determining the maximum viewing range.

All night vision devices sold by B&H have mechanisms in place to protect the intensifier tube from a sudden burst of bright light, but this does not mean that bright light doesn't damage the device.  Bright light in any form is not good for the longevity and performance of image intensifier tubes.
