Optical design of a spectrometer of high performance for planetary exploration

Fernández Rodríguez, M., Belenguer, T., Colombo, M., Cabrero, J. 2019. Optical design of a spectrometer of high performance for planetary exploration. Óptica Pura y Aplicada 52, 1, DOI: 10.7149/OPA.52.1.51007

It is presented the optical design of a visible compact spectrometer for the analysis of the elemental and geochemical composition of Mars ground. The spectrometer works in the spectral range from 533nm to 676nm achieving a spectral resolution of 0.14nm/px. The challenge of this design resides in assuring the instrument performance under demanding environmental conditions of operation (operative temperature from -40 degrees C to +6 degrees C and compatible with space radiation) and, at the same time, with very rstrictive conditions of mass and volume.
