Understanding SWIR Imaging

IR radiation extends from the red edge of the visible spectrum of light across a wavelength range of approximately 700 – 1,000,000 nanometres (nm). Within that spectrum are four distinct wavebands: near-infrared (NIR), SWIR, MWIR, and LWIR. How objects emit or reflect IR radiation is indicative of various physicochemical and thermal properties. For instance, materials exhibit characteristic SWIR absorption / reflection characteristics based on their distinct chemistries, enabling SWIR imaging to detect specific materials remotely.

SWIR refers to the portion of IR radiation adjacent to NIR, occupying a nominal wavelength range of 1,400 – 3,000 nm. We describe these wavelength ranges as approximations as there is no definitive standard of where each waveband separates…
