Yukon Advanced Optics, a world wide leader in the development and distribution of night vision and sporting 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.
Covert observation over a great distance at night can be the singular advantage that brings success to your mission. Being able to maintain your stealth and safety is a consideration to be taken seriously. Viewing through the 6.6x CS Governor Night Vision Biocular gives you the tactically advantageous flexibility to choose where and when you get set up. Biocular viewing is a compromise between binocular and monocular design, and offers benefits from both worlds. The reduced size and improved depth perception make this style NVD a favorite amongst many night vision professionals. Inside this rugged, well designed unit lies a third generation intensifier that lights up the night and delivers an astounding level of resolution (57-64 lp/mm). Out in front there's a very efficient 165mm f/2.0 objective that makes distant objects seem up close and personal. This is a serious and professional grade NVD that permits careful observation of any activity or location without you needing to disclose your position.
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 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. No matter what, bright light in any form is not good for the longevity and performance of image intensifier tubes.
