Infrared (IR) camera is a device that forms image using infrared radiations with operating wavelength of 14,000 nm. IR cameras were originally invented for military applications; however, these days, they are extensively adopted in other fields including archeology and medicine. It is used in night vision, building inspection, fault diagnosis, data center monitoring, chemical imaging, nondestructive testing, flame detectors, and others. Technological advancements in infrared imaging including incorporation of automatic functionality, built-in visual imaging, and development of infrared software to deliver affordable thermal analysis solutions have increased adoption across the world.
