Abstract

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°C to +6°C and compatible with space radiation) and, at the same time, with very rstrictive conditions of mass and volume.
