Step up to the next level in night vision technology with the ATN Night Storm WPT night vision monocular. Offering superior optical calibration at an economical cost, the Night Storm WPT--which comes in a stealth black color--is appropriate for a range of nighttime applications, including camping, wildlife observation, boating, and more. The monocular is made using white phosphor technology, which better detects the shades of intensity between white and black, resulting in improved contrast and depth perception. In fact, studies show that nighttime scenes appear remarkably more natural in black and white versus green, because black and white provides clearer information about contrast, shapes, and shadows. ATN also equipped the Night Storm WPT with a six-element, F1.2 50mm heavy-coated glass lens, which works with the first-generation intensifier tube to produce bright, crystal-clear images (up to 35,000 candlepower). And when you find yourself in a total darkness, you can take advantage of the Night Vision WPT's built-in infrared illuminator, which substitutes infrared for ambient light to help you see clearly regardless of conditions. Additional details include an optional camera/camcorder adapter (sold separately) that works with regular household cameras, letting you take detailed nighttime photos; a rugged, fully waterproof housing; contoured finger rests; a diopter adjustment of +/- 5 and a focus range of 1m to infinity; and ergonomically designed digital controls.

How Night Vision Works
All ATN night vision devices consist of several main parts: an objective lens, an eyepiece, a power supply, and an image intensifier tube (photocathode tube). The devices function by gathering existing ambient light, such as starlight, moonlight, or infrared light, through the front lens. This light, which is made up of photons, goes into the photocathode tube and is converted into electrons. Next, the device amplifies the electrons to a much greater number through an electrical and chemical process, and then hurls them against a phosphorous screen that changes them back into visible light. The image will appear through the eyepiece as a clear, black-and-white or green-hued, amplified re-creation of the scene you were observing. All night vision devices need some light to amplify. That's why all ATN night vision devices have a built-in infrared illuminator (IRI). An IRI essentially throws out a beam of infrared light that is near invisible to the naked eye, but your night vision device can see it. This allows you to use your scope even in total darkness. The IRI works like a flashlight, which is why the distance you can see with it is limited. Although ATN IRIs extend out to 100 yards, the IRI may cover only 40 to 60 percent of the viewing area.
How Far Can You See?
There are many different variables that can affect the distance you 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 (commonly called "recognition range"), or are you just trying to see if something is there? Maybe you will see just the movement, but won't be able to determine 100 percent who are what it is. This is called "detection range." Another variable is lighting conditions. The more ambient light you have, 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 than if it's cloudy and overcast. ATN typically states that you can tell the difference between a male and 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.
