The Airborne Visible and InfraRed Imaging Spectrometer 3 (AVIRIS-3) is an imaging spectrometer with a two-mirror telescope and Dyson-type spectrometer which are optically fast (F/1.8), span a wide swath (40-degree field of view over 1240 spatial pixels), and operate over the 380-2500 nm solar-reflected spectrum with 7.4 nm spectral sampling.  The spectrometer is identical in design as the EMIT spectrometer now operating in orbit on the ISS.
