US NightVision Corporation has a reputation as a leading manufacturer and distributor of the latest and highest quality night vision and tactical equipment that is known world wide. Their dedication to customer service, satisfaction and support is exemplary and sets an extremely high standard for the entire industry. Whether you're looking for body armor, a thermal imaging weapon sight, or a hands-free night vision goggle, USNV has a huge selection for you to choose from.
The lightweight and extremely versatile USNV-18 night vision monocular can be operated hand-held, head, helmet, or weapon mounted, or fitted to a camera/camcorder.
The optical system of the USNV-18 is configured with a 1.0x, or unity, level of magnification. This allows the operator to employ a both-eyes-open approach to nighttime operations. This battle-proven concept maximizes depth-perception and situational awareness with enhanced peripheral vision.
This NVD is constructed with a durable housing that's engineered to provide ergonomic functionality under tough conditions. Its optical system is based upon fast high-resolution multicoated lenses, and a potent second generation intensifier for clear viewing under low or no-light conditions. This monocular is fitted with a Photonis-Dep commercial spec. tube that compares favorably with third generation imaging systems.
There are many different variables that affect the distance that one can see with a night vision device, among them the object's size, the level of details being sought from the object and the conditions of observation. 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 the method of calculation varies by manufacturer. The important factors to consider when evaluating any night vision device are the intensifier tube's generation, s/n ratio, level of magnification, specified resolution, along with the clarity & light transmission efficiency of the optical system.
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. No matter what, bright light in any form is not good for the longevity and performance of image intensifier tubes.
