Scientific paper

The CHRIS instrument is a space-based imaging spectrometer that will provide 10 nm spectral resolution over the spectral range from 415 nm to 1050 nm. The nominal spatial sampling interval will be 25 m, however, larger sampling intervals are possible. Band selection, spectral bandwidths and the spatial sampling interval will be programmable. The instrument is planned to be launched on an agile small satellite of the 100 kg class. This satellite will operate in a sun-synchronous, high inclination orbit at approximately 830 km. At this altitude the instrument can provide 19 spectral bands with a spatial sampling interval of 25 m at nadir. The field of view of CHRIS is 18.6 km. Attitude control of the platform will allow access to non-nadir targets, multi-angle observations of selected targets and improved radiometric resolution. This paper describes the optical design of the instrument, including the telescope, spectrometer detector and in-flight calibration hardware, as well as critical alignment procedures, with emphasis on spectrometer assembly and stray light control. Results of performance and calibration measurements are presented.
