The visible and near-infrared (VNIR) portion of the electromagnetic spectrum has wavelengths between approximately 400 and 1100 nanometers (nm).[1] It combines the full visible spectrum with an adjacent portion of the infrared spectrum up to the water absorption band between 1400 and 1500 nm. Some definitions also include the short-wavelength infrared band from 1400 nm up to the water absorption band at 2500 nm.[2] VNIR multi-spectral image cameras have wide applications in remote sensing and imaging spectroscopy.[3] Hyperspectral Imaging Satellite carried two payloads, among which one was working on the spectral range of VNIR.[4]
electromagnetic radiation at wavelengths extending from 100 nm in the ultra-violet, through the visible (400-700 nm), and the near infrared (700-1400 nm), to the far infrared (1400 nm – 1 mm).
