Infrared radiation which has a wavelength between 0.7 μ‎m and 2.5 μ‎m. Near-infrared is subdivided into very-near infrared (0.7 μ‎m–1 μ‎m) and short-wave infrared (1.0 μ‎m–2.5 μ‎m). Photographic films respond to wavelengths between 0.7 μ‎m and 1.0 μ‎m, hence very-near infrared is also known as photographic infrared.
