IDEX Health & Science Semrock optical filters are on NASA’s new Perseverance rover that will try to definitively answer whether life ever existed on Mars. Working with NASA’s Jet Propulsion Laboratory (JPL), our optical filter team developed filters for the SHERLOC instrument, which will enable the rover to identify, collect and store rock and soil samples from Mars. The SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) instrument is an arm-mounted, Deep UV (DUV) fluorescent spectrometer, which enables the rover to spatially resolve, and detect the characterization of organics and minerals in the Martian surface. The instrument is used to assess past aqueous history, detect the presence and preservation of potential biosignatures, and to support selection of return samples.
