WebSHERLOC’s neon-copper laser supports simultaneous Raman and fluorescence emission detection through 268.6-nm excitation. One of the instrument’s most recent discoveries came last August with the observation of fluorescence from organics that were co-located with minerals such as olivine and carbonate, suggesting an abiotic formation of organics. WebJul 31, 2014 · SHERLOC will shine a tiny dot of ultraviolet laser light at a target. This causes two different spectral phenomena to occur, which the instrument captures for analysis. … dr bruce mcdonald wichita falls tx

WebAbstract: The SHERLOC instrument (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) is an ultraviolet (UV) Raman and fluorescence spectrometer that will be deployed on the Mars 2024 rover mission. The instrument includes a context microscopic imager with resolution of $10\ \mu\mathrm{m}$, and the scanning … WebMar 1, 2014 · SHERLOC uses a deep UV resonance Raman and fluorescence spectrometer utilizing a 248.6 nm deep UV laser for noncontact sample analysis. The technique may modify organics by inducing reactions with ... WebFeb 9, 2024 · SHERLOC spectra have a ∼10 cm −1 /pixel resolution with a Raman spectral range of ∼800–4,000 cm −1. The potential to observe Raman bands in the spectral range below 800 cm −1 is limited because SHERLOC's laser-injection filter has reduced transmission in this region and the 252.9 nm laser plasma line is observed at ∼650 cm −1. dr bruce mccormick shreveport
