What are SWIR, MWIR, and LWIR – And what do they mean?

The three wavelengths are: Short Wavelength Infrared (SWIR), Medium Wavelength Infrared (MWIR), and Long Wavelength Infrared (LWIR). All Thermal imaging devices operating on the infrared wavelength are, ‘ imagers ‘ that we commonly refer to as ‘ cameras’, however they are actually sensors that can detect radiated heat.

Weather Satellites/Sensors - NRCan

It has two fairly broad wavelength bands: a visible and near infrared band ( to μm) and a thermal infrared band ( to μm). An interesting feature of the sensor is its ability to acquire visible band night time imagery under very low illumination conditions. With this sensor, it is possible to collect striking images of the Earth showing (typically) the night time lights of ...

The Working Principle and Key Applications of Infrared Sensors

· The Types of Infrared Sensors. Infrared sensors can be active or passive and they can be split into two main types: Thermal infrared sensors – use infrared energy as heat. Their photosensitivity is independent of the wavelength being detected. Thermal detectors do not require cooling but do have slow response times and low detection capabilities.
