Newcon Optik NS-156 2.4x 1st Generation Night Vision Rifle Scope
The NS156 is the latest addition to Newcon's family of weapon scopes. It meets the growing demand for an affordable nightvision weapon scope without skipping on quality or features.
There are many different variables that effect the distance that one can see with a nightvision device, among them the object's size, the level of details being sought from the object and the conditions of observation. Nightvision 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 nightvision 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.
