Thermal Imaging Optical devices are powerful optical tools combining a thermographic camera with a set of optics. A thermographic camera (also called an infrared camera or thermal imaging camera) is a device that forms an image using infrared radiation, similar to a common camera that forms an image using visible light. Instead of the 400–700 nanometer range of the visible light camera, infrared cameras operate in wavelengths as long as 14,000 nm (14 µm). Their use is called thermography.
Thermal Imaging Optics category includes devices like thermal riflescopes, binoculars, goggles, hand held monoculars and cameras, vehicle mount cameras and other similar optics. Unlike the regular night vision technology, thermal imaging displays images based on their temperature signature. This makes them much more capable then night vision. Another advantage of thermal imaging is the lack of sensativity to bright light.
