A thermo graphic camera or thermal 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 450–750nm range of the visible light camera, infrared cameras operate in wavelengths as long as        14 000nm (14µm), creating an image from the heat omitted.

 Applications

Originally developed for military use during the Korean War, thermo graphic cameras have slowly migrated into a variety of fields ranging from medical through to archaeological applications. More recently, the lowering of prices have helped fuel the adoption of thermal viewing technology. Advanced optics and sophisticated software interfaces continue to enhance the versatility of thermal cameras.
