The spectral response range of a SWIR (Short-Wave Infrared) sensor refers to the range of wavelengths of electromagnetic radiation that the sensor is capable of detecting and capturing. SWIR sensors typically operate in the short-wave infrared spectrum, which ranges from approximately 900 nanometers (nm) to 2500 nm. This range falls between the visible and thermal infrared portions of the electromagnetic spectrum.

The spectral response range of a SWIR sensor determines the specific wavelengths of light it can detect, which in turn describes its suitability for different applications. For example, some SWIR sensors might be optimized for certain wavelengths to enhance visibility through haze or to detect specific materials based on their spectral signatures.
