With a super fast lens system, the Night Leopard CGT from ATN produces as bright an image as can be expected from its 2nd generation design. The easy push button controls, 3x magnification and built-in infrared illumination are just a few of the features this scope packs. It is truly an excellent compact, high quality night vision monocular. Peak resolution from the Gen 2+ intensifier tube is specified as 40-50 linepairs per millimeter. Of course the anti-blooming & highlight resolution improvements found in 2nd generation design are present here as well; light gain as compared to Gen 1 is incredibly well improved.
There are many different variables that effect 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. Bright light in any form is not good for the longevity and performance of image intensifier tubes.
