COMPONENTS AND CONSTRUCTION
• Although the optics play a critical role in overall quality of the Night Vision device, the heart of an NVD and the most important component is the Image Intensifier Tube (IIT). As one of the worlds largest consumers for IITs, we source and acquire the best and the latest available image intensification technologies from top US and European producers. From hand selected premium grade 1st Generation to 3rd Generation that would satisfy the most performance obsessed military clientele, ATN offers the best for your specific application.
• To guarantee the optimum performance of the Image Intensifier Tube we build our own power supplies. This is where the latest electronics transform into a myriad of features and outstanding reliability.
• Our attention to detail is especially apparent when it comes to construction. Materials range from titanium, aircraft quality aluminum alloys to hi-impact plastic composites. 1/8 MOA adjustments on our weapon scopes is an excellent example of what our CNC machines can do. We finish the job with O-rings, nitrogen purging and a hard exterior powder coating. This process makes our units virtually immune to all weather conditions. |

SELECTION AND INNOVATION
• ATN manufactures the world’s largest selection of night vision devices. From 1st Generation to 4th Generation, our line includes pocket scopes, monoculars, binoculars, bi-oculars, goggles, weapon sights, multi-application units and Day/Night systems - more then 100 different models overall. No matter what your need in a night vision device is, we have the scope for you.
• When you see night vision units with built-in Infrared Illuminators for total darkness capability, remember that ATN was one of the first to offer this feature that has now become an industry standard. All of our units are outfitted with an IR and some of the models come with the most powerful in the industry 450mW Long Range version. ATN was also the first to offer interchangeable lenses, optical doublers and remote controls for night vision devices. We now hold many Patents and our patent portfolio is expanding every year.
• Our R&D engineers are making sure that ATN is always on the cutting edge providing you with the latest in features and technology.

HOW STARLIGHT TECHNOLOGY WORKS
All Starlight technology Night Vision Devices consist of several main parts: an objective lens, an eyepiece, a power supply and an image intensifier tube (Photocathode Tube).
Night vision devices gather existing ambient light (starlight, moonlight or infra-red light) through the front lens. This light, which is made up of photons goes into a photocathode tube that changes the photons to electrons. The electrons are then amplified to a much greater number through an electrical and chemical process.
The electrons are then hurled against a phosphorus screen that changes the amplified electrons back into visible light that you see through the eyepiece. The image will now be a clear green- hued amplified re-creation of the scene you were observing.

HOW FAR YOU CAN SEE
There are many different variables that can affect the distance you can see with a Night Vision device. First, what are you trying to see? Are you looking for another boat on the water or are you looking for a rabbit in the woods? The larger the object the easier it is to see. Plus, are you trying to see details (what we call recognition range) or are you just trying to see if something is there? Maybe you will just see the movement, but won’t be able to determine 100% who or what it is. This is called “detection range”. A second variable is lighting conditions. The more ambient light you have (starlight, moonlight, and infrared light) the better and further you will be able to see. You can always see further on a night where the moon and stars are out, then if it is cloudy and overcast. We typically state that you can tell the difference between a male and a female or a dog and a deer at about 75 to 100 yards. However, if you were looking across an open field and there was a half moon out you could see a barn or a house 500 yards away. Remember, that the purpose of an NVD is to see in the dark not necessarily at a long distance like a binocular. |
