Kelvin Infrared

Notorious night-vision devices, although related to night vision devices, but they work, usually in the higher parts of the spectrum, and require that at least some of vneschnego lighting or even infrared illuminator, so that this is not exactly what will be discussed. In the course of normal pitch darkness of night vision devices are not very much good, however, have no say about rabtayuschie at low frequencies thermographic device. This type of devices capable of receiving termoizluchenie remote sites and convert it into visible images. A few years ago they were worth big money and is a very dimensional devices, today these technologies, proposed in the 'new package'. And they are suitable for mass use. Thermal radiation is created by any object at a temperature above zero degrees Kelvin, or -273 C. To visualize this radiation requires special equipment or infrared camera.

The American company Flir, known for its technology in the industry thermography offers consumer portable and very compact black and white thermographic camera, designed for a wide range of uses, like power structures, researchers are studying the night life and even children! Of course the usefulness Oonah will of the above categories the issue rather controversial, but one thing is fairly - 'toy' has turned out quite entertaining. And who will use it is a question of another harakreta. The price of this device, however, very 'grown-up - 3000 dollars. At the same time, it is essential cheaper military samples thermographic devices with approximately the same characteristics. We recall once more that the usual infrared survey of the radiation corresponds to a temperature between 250 C and 500 C, while the range of thermography much more widely: from -50 C to over 2000 C.
