Ocean Optics Spectrometers Head to Mars
Ocean Optics supplied three modular HR2000 high-resolution miniature fiber optic spectrometers that were configured for analysis of Martian rock and soil composition using Laser Induced Breakdown Spectroscopy (LIBS). A laser mounted to the mast unit of the ChemCam instrument can fire at targets up to nine meters away, generating a series of laser pulses, the light from which is collected for the LIBS analysis.
Each ChemCam spectrometer is configured to detect elemental signatures over a different wavelength of light: 240-336 nm, 380-470 nm, and 470-850 nm. The use of the three spectrometers simplifies the design and creates redundancy, as many elements under study have spectral lines in more than one of the spectral ranges covered by the three units.
The Curiosity Rover has been described by NASA as having the most advanced scientific instrumentation ever used to study the surface of Mars. With the analysis enabled by Ocean Optics’ equipment, sample analysis is exponentially faster. On prior missions, the time required to determine composition of a single sample was two to three days; ChemCam’s output is anticipated to be one dozen compositional measurements per day.
