These can be divided into two types cooled and.
Long wave infrared sensor.
One type collects information in wavelengths between 3 0 and 5 0 micrometers these wavelengths are actually medium range infrared but are grouped with the lwir type.
In order to see radiated heat special lenses and sensors are needed to focus and detect electromagnetic radiation in the mwir mid wave infrared and lwir long wave infrared ranges.
Very long wave infrared vlwir 12 to about 30 μm covered by doped silicon.
Mid and far infrared are progressively further from.

Long wave infrared lwir is a remote sensing technique that is also referred to as thermal imaging.
This is the radiant heat that uncooled thermal imaging cameras see.
To detect thermal energy special fpas focal plane arrays are required.
Using focal plane arrays of either 160x120 or 80x60 active pixels lepton easily integrates into native mobile devices and other electronics as an ir sensor or thermal imager.
8 to 12 or 7 to 14 μm this is the atmospheric window covered by hgcdte and microbolometers.
There are two types of long wave heat sensors used to collect geothermal data.
Long wave or lwir infrared is a subset of the infrared band of the electromagnetic spectrum covering the wavelengths ranging from 8µm to 14µm 8 000 to 14 000nm.
