Thermal Camera Spectral Range

The temperature of a body can be determined on the basis of its emitted radiation in the infrared spectral range.

Thermal camera spectral range.

Spectral range is the range of wavelengths that the sensor in the camera detects measured in micrometers µm. The visible spectral range has wavelengths from 380 nm to 780 nm. The workswell gis 320 ir camera is an mwir thermal camera designated for unmanned aircraft drones. 1 this thermal camera has a cooled insb detector a resolution of 320 240 px and a spectral range of 3 2 3 4 μm.

Each type has its own place in facilities maintenance depending on use and operation.

Infrared thermography irt thermal imaging and thermal video are examples of infrared imaging science.

Almost all other thermal cameras are longwave and have a spectral. The maximum of the blackbody radiation emitted according to planck s law of radiation is at relevant temperatures in the infrared spectral range between 0 78 μm. Short wavelength mid wavelength and long wavelength. A thermographic camera also called an infrared camera or thermal imaging camera or thermal imager is a device that creates an image using infrared radiation similar to a common camera that forms an image using visible light instead of the 400 700 nanometre range of the visible light camera infrared cameras are sensitive to wavelengths from about 1 000 nm 1 μm to about 14 000 nm 14 μm.

Short wavelength infrared cameras typically detect infrared wavelengths in the spectral range of 0 9 1 7 microns which is very close to the visible light spectrum. Consequently most insb camera systems are designed to operate either as a nir imager in a range from 1 to 3 µm or as a thermal imager in the 3 to 5 µm range but not both. Most gas detection cameras such as propane methane and butane detectors are midwave cameras meaning they have a spectral range of 2µm to 5µm. Infrared cameras come in three basic types.
