The 0.5 milliradian field of view means that VIMS will resolve a 0.5 km spot at a distance of 1,000 km. By mosaicing multiple fields of view, VIMS will produce images of Saturn, its rings and moons comparable to and sometimes better than Voyager images, but with full 352 spectral channels at each pixel. The spectral range and spectral resolution will allow detailed compositional mapping of minerals on the satellites and rings of Saturn, and of gases in Saturn's atmosphere. VIMS will image surface detail on Titan at infrared wavelengths, cutting through the thick haze which blocks views of the surface at visible wavelengths.
