VNIR ia an initialism for visible and near-infrared, a portion of the electromagnetic spectrum having wavelengths between approximately 400 and 1400 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 1400nm up to the water absorption band at 2500nm.[2] VNIR multi-spectral image cameras have wide applications in remote sensing and imaging spectroscopy.[3]
