Most people wouldn't think about owning their own thermal vision goggles, but plenty of people have seen them in films to know what they are. They are typically the subject of spies infiltrating bases and the like, but they do have their real-life uses. In the real world, these types of devices are used by soldiers or law-enforcement officers who use them for security and surveillance, while some people also use them for activities such as hunting or camping.
There are two different types of night vision technology to chose from: thermal imaging and image enhancement. Image enhancement collects small amounts of light, including the lower portion of the infrared light spectrum, which is not usually visible to the human eye, and magnifies it so that surroundings can easily be seen.
The technology behind thermal vision goggles works by imaging the upper part of the infrared light spectrum. This light is emitted through the heat of an object and the goggles capture portions of the heat that is given off. The viewer sees the heat of whatever is being focused on, but does not get a crisp image. The hotter the object, the more light is emitted and shown in the viewfinder. A living creature or human will give off more infrared light than an inanimate object such as a tree or rock.
These types of goggles can come in head-equipped and handheld variations. The goggles may have a single lens or two eye pieces, though that depends on the model. A spotting scope for focusing in on a target is also something consider. Goggles that strap to the head are the best choice when the activity requires an abundance of moving around, they rest securely on the head and keep your hands free.
The other benefit to thermal imaging models is that the reflection of light is not required to see a living animal in complete darkness. With the right kind of thermal vision goggles, objects can be seen in the dark or in extreme weather conditions over 200 yards away.
You can find several different models and styles, and usually require only two AA batteries to operate. You can find thermal vision goggles at just about any sporting or camping store, and they are relatively cheap. These types of goggles are a great present for anyone who enjoys camping, hiking or hunting and they also can bring something new to an outing.
