Short-wave infrared (SWIR) is a portion of the electromagnetic spectrum that ranges from approximately 1,000 to 2,500 nanometers in wavelength. SWIR light is invisible to the human eye but can be detected by specialized sensors and cameras. SWIR imaging has applications in various fields including agriculture, security and surveillance, medical imaging, and environmental monitoring. This technology can penetrate haze, fog, and smoke, allowing for clearer imaging in challenging conditions. SWIR imaging can also be used for material analysis, such as identifying different types of plastics or minerals.
