For practical purposes when we refer to ‘IR cameras’ in the industrial camera world we mean cameras existing in the non-visible regions indicated above. However, an important distinction and to be more correct scientifically speaking, thermal imaging is referred to as imaging in the MWIR and LWIR bands. The reason for this is that terrestrial objects emit light at those wavelengths. Quite simply the higher the object’s temperature the brighter the object will appear in thermal imaging.
Rice’s Midwave IR (“MWIR”) cameras operate in the mid-infrared spectrum at 3-5 micron, with some models extending from the SWIR to MWIR range with 1.5-5 micron sensitivity. These cameras are equipped with highly sensitive infrared sensors and provide the utmost in MWIR imaging capabilities. Due to the high-performance nature of these cameras they are geared toward research in the fields of scientific, military, or industrial applications. Rice’s MWIR cameras require a larger investment than other types of thermal cameras and are for those U.S. organizations that can afford to choose the very best IR camera.
