TerraSpec Halo

TerraSpec Halo

Analytical Spectral Devices (ASD) NIR

The TerraSpec Halo mineral identifier is the world’s only hand-held full-range NIR spectrometer, measuring the visible and shortwave infrared regions (350-2500 nm).

With a push of a button, the TerraSpec Halo delivers results in seconds; a rapid method to identify minerals and decrease associated exploration costs. Onscreen results are delivered via a proprietary mineral prediction software program gathering data from a vast mineral library obtained from some of the world’s top mineral databases.

Optimised for the demands of of its users.

TerraSpec NIR Spectrometers

Analytical Spectral Devices (ASD) NIR

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 geological exploration, using full-range near infrared technology.

The TerraSpec 4 Standard-Res mining analyser is ideal for a range of mining production measurement applications, including heap leach optimization, ore sorting, agglomeration optimization, and floatation ore feed control.

The TerraSpec 4 High-Res analyser with 6nm resolution enables you to determine the viability of mineral exploration targets quickly and precisely.  Enhanced optics provide even higher quality spectral results. This improved data quality of the TerraSpec High-Res analyser allows for accurate assessment of low-concentration and low-reflectance minerals.

  • High-res and standard-res options
  • Non-destructive, reliable analysis
  • Portable and built for endurance
  • Unparalleled alteration mineral analysis
  • Rapid key mineral identification
