Their products are designed with diligence and technological advancements that have made them a world leader in providing sporting and tactical optics. Their high quality optical designs are loaded with user friendly features, and offer value and functionality that deserve recognition and merit.
ATN's NVB5X-2IA is a high-powered biocular with outstanding night vision performance. Bi-ocular viewing combines the best features of monoculars and binoculars. The configuration of two oculars with a single objective and intensifier tube delivers power, performance, and comfort combined with less mass, weight, and cost.
Sitting out in front of this impressive NVD is a remarkable 5x afocal lens. This high-performance optical enhancement has a tremendous positive impact upon your range of recognition and detection. The mission-critical advantage of covert target observation puts you in the driver's seat and nearly ensures your success. For optimum viewing performance under poor or nonexistent lighting conditions the included high-powered IR illuminator can be deployed for enhanced levels of observation.
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.
