optics, stay true to their one simple mission; to produce high quality optics at affordable prices. Their items are lightweight, compact, and quite durable. Extreme care is taken in the construction and design of each optic, and special attention is paid to the art and physics of optical science. This level of quality control ensures that each device is a joy to hold, use, and look through. The excellent optics and light intensification system of Yukon's Exelon 3x50 Night Vision Monocular delivers a fabulous viewing range and a high degree of detailed recognition. The Exelon is designed with fine ergonomics; this NVD feels and operates comfortably and intuitively in your hand. While the larger objective presents a notable profile, this device is still small enough to transport easily. Combined with an optional photo adapter and supplementary IR illuminator, the EXELON becomes part of a formidable nighttime surveillance system. 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.
