Instrument

Arago is a space mission consisting of a 1-meter Cassegrain telescope, equipped with a polarimeter feeding two spectrographs working in the UV [119-320] nm and Visible [355-888] nm spectral range and using cross-dispersion techniques to reach the required spectral resolution (25000 in the UV and 35000 in the Visible). The detectors are CMOS sensors.
