The Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals (SHERLOC) instrument suite includes a deep ultraviolet (DUV) Raman and fluorescence instrument on the robotic arm of the Mars2020 (M2020) Perseverance rover [1]. When sufficiently thick dust coatings are present, substrate surfaces are not detected, and mineralogical information not obtained. For example, the effect of palagonitic dust coatings as a function of depth to various substrates on thermal emission, VNIR, and Mössbauer spectra are reported by [2, 3]. In this study, we use the same palagonitic dust to study the effect of dust coating thickness on DUV Raman spectra.
