ATN's Aires MK7700-B Smart Series riflescope is a true Aries night vision weapon scope. ATN manufactures a large line of night vision weapon sights, utilizing current military designs to develop commercially available advanced NVD riflescopes. The "Red on Green" rear projection aiming system provides the user with a sharp reticle allowing fast, effortless target acquisition. The system increases the reticle sharpness by 600% over standard NVD riflescopes, and unlike some less expensive scopes it is equipped with a 1/8 MOA internal windage elevation system. The MK7700-B uses a 3rd generation image intensifier tube, with exceptionally good lowlight visibility. The Gen 3 units add a sensitive chemical, gallium arsenide, to the photocathode for a brighter and sharper image over 2nd generation designs. The MK7700 is available in two 3rd generation distinctions, with the MK7700-B providing measured resolution of 51-64 linepairs per millimeter.
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.
