In 1993 and 1996, laboratory measurements were conducted at the Instrument Services Laboratory (ISL) at the Center for Research in Earth and Space Technology (CRESTech) in order to characterize the spectral bandwidth. Results demonstrate that the spectral bandwidth of the casi decreased due to improvements made by the manufacturer, ITRES. The shape of the bandpass curve as a function of wavelength also changed significantly. In 1993, it was very wavelength dependent with a parabolic shape, while in 1996 it was less wavelength dependent. Spectral bandwidth departures from nominal values across the sensor's field of view, spectral range and operating f/# were documented.
