ATN, an established leader in the world of night vision and tactical optical designs, offers many options for the professional, military, law enforcement and discerning user of night vision devices. Their products are designed with diligence and technological advancements that have made them a world leader in providing sporting and tactical optics. Their high quality optical designs are loaded with user friendly features, and offer value and functionality that deserve recognition and merit.
The ATN 4-12x80-2I is a day & night vision sighting system for your long-range precision firearm. Changing from day to night vision is simple, quick, and does not affect your point of impact. The unprecedented combination of an 80mm objective lens with a 40mm main tube sits the scope up high, and delivers a brilliant sight picture all day long.
When the sun dips below the horizon, you can install the night vision ocular and keep on shooting. The night vision eyepiece is fitted with a high-quality image intensifier tube with outstanding resolution performance. When total darkness conditions prevail, the IR illuminator is capable of providing the necessary supplemental illumination you'll need to get on target without being seen.
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.
Rugged 40mm main tube is milled from high quality aircraft aluminum
4-12x Magnification Range
Extreme versatility is found with a range of 4-12x. 4x is favored for moving game, & target acquisition within close quarters, while 12x allows for all but the very longest of shots. (Range of focus: Daytime: 50yd-infinity, Nighttime: 75yd-infinity)
Long Range Target Acquisition
Powerful 450mw infrared illuminator for long-range target acquisition
Touch-pad switch system allows you to illuminate the scene at your discretion
Day and Night Vision Versatility
This riflescope comes with two oculars, one for day-time use and the other is a high quality night vision eyepiece.
Bullet Drop Compensation Cams
Interchangeable cam system provides repeatable correction for long-range precision shooting Cams included with purchase: 50 BMG, .308, 30-06, .270,
7mm Mag, .300 Win Mag, 22-250, .223, .243)
Fine Windage & Elevation Correction
1/8 MOA precision adjustments with 12.5 MOA windage and elevation correction
Illuminated Rangefinder Reticle in First Focal Plane
The rangefinder reticle facilitates accurate distance ranging calculations. Three posts and and a centered dot establish your point of aim. A series of hash marks in the lower right quadrant provide a reference for gauging the distance to a object of a known dimension.
First focal plane positioning of the reticle maintains its subtension across the magnification range.
The illumination feature offers 9 brightness levels, and an off position.
Second Generation Intensifier Tube
Second generation intensifier tube delivers 40-45 lp/mm of resolution (FOM <350)
Second generation intensifiers are less reliant upon ambient light, produce clearer images with less distortion, and last longer than earlier versions of night vision technology.
