ASD TerraSpec® 4 Hi-Res Mineral Spectrometer
Fast, precise mineral exploration
Recognized as the de facto technology for mineralogical analysis, the rugged portable ASD TerraSpec??mineral spectrometers are trusted by top?geologists for performing fast, precise pathfinder mineral identification for identification of exploration targets. The ASD TerraSpec 4 Hi-Res mineral analyzer?brings new levels of efficacy to mineral exploration technology. This state-of-the-art mineral spectrometer offers enhanced performance in the SWIR 1 and 2 regions and a 6 nm resolution to help you determine the viability of mineral exploration targets faster and more precisely than ever before. These enhancements provide you with the ability to capture accurate spectral data more quickly, especially for samples with darker mineral features.
For mining exploration geologists, these improvements translate into faster data capture at exploration targets and drilling sites. The improved data quality provided by the ASD TerraSpec??4 Hi-Res mineral spectrometer also allows for accurate assessment of low-concentration and low-reflectance minerals, like iron-containing minerals such as serpentines and chlorites, which were previously difficult to measure. Benefits include:
- Enhanced optical configuration provides more precise spectral results for superior spectrum clarity and definition.
- Industry leading performance in the SWIR 1/SWIR 2 regions for unparalleled alteration mineral identification.
- Standard ruggedized steel covered fiber optic cable ensures consistent spectral quality.
- No need for sample prep, which means fast field scans.
Pair the ASD TerraSpec 4 Hi-Res mineral analyzer with The Spectral Geologist (TSG) software from Spectral Geoscience to analyse the spectra and produce mineralogical output products.
