The SuperCam infrared spectrometer for the perseverance rover of the Mars2020 mission

We present the Infrared spectrometer of SuperCam Instrument Suite that enables Mars 2020 Perseverance Rover to study remotely Martian mineralogy within Jezero crater. The IR is designed acquire spectra in 1.3–2.6?m domain at a spectral resolution ranging from 5 20 nm. field-of-view 1.15 mrad, coaligned with boresights other remote-sensing techniques provided by SuperCam: laser-induced breakdown spectroscopy, remote time-resolved Raman and luminescence spectroscopies, visible reflectance micro-imaging. can be acquired robotic-arm workspace long-distances, order explore mineralogical diversity crater, guide its sampling task, document samples’ environment. design, performance, radiometric calibration, anticipated operations surface Mars.
