Abstract: A spectrophotometric device is disclosed having a plurality of spectral measurement bands including a single telescope and a single spectrophotometer. The plurality of spectral bands is obtained by placing pupillary separating prisms at an entrance pupil of the telescope, and by using spectral band selection filters. Such a device has a lower weight, smaller dimensions, and a lower price. In particular, it may be integrated into a satellite, in particular for a mission to characterize flows of carbon compounds that are produced on the Earth's surface.
