Initially conceived to perform chemical and mineralogical testing for NASA’s Mars Science Laboratory (MSL) mission, Olympus’ Terra™ is a rugged, fully portable field instrument which harnesses advanced dual XRD/XRF technology and renders it for earth- bound applications. Combining both Olympus and NASA innovation, Terra brings to life a new way of performing X-ray diffraction and X-ray fluorescence measurements. Using a specifically developed direct excitation charge coupled device (CCD) “camera”, Terra is able to collect X-ray photon data for both X-ray diffraction and X-ray fluorescence simultaneously. This is the result of the integrated camera’s ability to detect both photon position and photon energy at the same time. With energy resolution of ~200 eV (5.9 keV), Terra makes XRF analysis as simple as viewing the software spectrum display.
