Imaging Science Subsystem (ISS) The Cassini Imaging Science System was specifically designed for exploring the Saturn system, and includes spectral filters and imaging capabilities for a multitude of scientific objectives, including capturing lightning, investigating the three dimensional cloud structure and meteorology of the Saturn and Titan atmospheres, imaging the surfaces of its many icy satellites, determining the composition and structure of its enormous ring system, and peering through the hazy Titan atmosphere down its still unexplored surface.
The ISS consists of two framing cameras. The narrow angle camera is a reflecting telescope with a focal length of 2000 mm and a field of view of 0.35 degrees. The wide angle camera is a refractor with a focal length of 200 mm and a field of view of 3.5 degrees. Each camera is outfitted with a large number of spectral filters which, taken together, span the electromagnetic spectrum from 2000 Angstroms to 1.1 microns. At the heart of each camera is a charged coupled device (CCD) detector consisting of a 1024 square array of pixels, each 12 microns on a side. The data system allows many options for data collection, including choices for on-chip summing and data compression.
 For a detailed description of the Imaging Science Subsystem, its observational capabilities, and the Cassini Imaging Team's science objectives at Saturn, see the Imaging Team's report "Cassini Imaging Science: Instrument Characteristics and Anticipated Scientific Investigations at Saturn," published in 2004 in the journal Space Science Reviews. For additional information about the Cassini spacecraft, its mission and instruments, see JPL's Cassini site. While the Imaging Science Team was responsible for guiding the development of the cameras and ensuring their scientific utility, the following individuals at the Jet Propulsion Laboratory played major roles in the actual building and testing of the cameras between the years 1990 and 1997:
