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.
Overview
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.

Probes and Lighting
Contact Probe
The ASD Contact Probe is designed for contact measurements of solid raw materials such as minerals, grains, other granular materials. Its innovative optical design minimizes measurement errors associated with stray light and allows for measurement of samples through clear and transparent plastic bags.
In addition to the standard contact probe, ASD also offer the Hi-Brite contact probe and the Plant Probe.
All contact probes are available with a ruggedized cable feed and cable, designed for applications that involve extra cold or harsh temperatures. (see image below specifications)

Rapid Analysis Probe
The Rapid Analysis Probe is specifically designed for speedy spectral collection of powders and other fine-grained materials such as small uniform seeds and grains. Its beveled tip and metal jacket greatly speed up the spectral collection process of fine grained materials to optimize workflow. Simply insert the Rapid Analysis Probe into your fine-grained media, collect the spectrum, use a chemical wipe to swipe the probe clean and move on to the next sample. It’s that easy! The Rapid Analysis Probe comes with a gimbaled white reference for high performance calibration. It can be used for quantitative predictive models.
If using this probe with a spectrometer such as a TerraSpec mineral analyzer or a LabSpec lab analyzer without an integrated light source, a Fiber Optic Illuminator is necessary. The Fiber Optic Illuminator provides the light source needed for sample collection.
