Features and benefits
The ASD TerraSpec Halo handheld spectrometer delivers rapid mineral identification that significantly speeds exploration efforts, increases efficiency, improves analysis and decision making, and ultimately saves exploration programs valuable time and money. Benefits include:
Lightweight design and ruggedness allow for unprecedented portability. The fully integrated, full-range spectrometer with on-board mineral identification software eliminates the need for cumbersome cables or third-party devices.
- Fast and accurate
Powerful on-board software allows for mineral results in seconds, including confidence rating and spectral scalars that give you even more information about your deposit.
- No cables
Don’t get tangled up in fragile cables from your spectrometer to your contact probe. And don’t worry about putting down your third-party PDA and losing it. The TerraSpec Halo is an all-in-one device – one hand, one click.
- Simple mineral data capture and handling
Data can be automatically saved on the instrument and later exported to any Windows computer. Use the intuitive Halo manager software for easy file naming, clear graphical spectrum and results review, and unprecedented spectrum management and export tools.
- No more lost notes or locations
GPS and voice memo features allow you to geotag and record audio notes with every measurement.
- Immediate multi-mineral results and scalars
TerraSpec Halo doesn’t give you just one mineral prediction. It gives you multi-mineral predictions, confidence levels and spectral scalars that allow you to monitor crystallinity changes, subtle shifts in alteration patterns and compositional changes associated within geochemical gradients.
- Extensive spectral library
Comprehensive multi-continent spectral library.
- User-friendly features
Highly portable, the TerraSpec Halo is designed with audio and visual tools for easy operation, fast data collection and superb workflow. With a few clicks, optimize performance for both light or dark rocks.
- No third-party hardware
Everything you need for the field is on the device. Download your spectral data from the TerraSpec Halo to your own laptop where you can export the data to The Spectral Geologist (TSG®), Leapfrog or other third-party software tools of your choice.
- Spectrum management
Review spectra on the device or on your laptop. Laptop software allows for easy spectrum management with user-friendly file naming, spectrum review and tagging, and easy import/export capability.
The output from the ASD TerraSpec Halo can be exported to be used by The Spectral Geologist (TSG) software from Spectral Geoscience to provide additional analysis of the spectra and produce mineralogical output products.
ASD’s spectroradiometers have been used for decades for remote geologic interpretation. The ASD TerraSpec Halo mineral identifier can be used in many industry applications, including:
Petroleum geologists utilize ASD instruments for improved definition of deposit mineralogy, real-time strata correlation, hole stability monitoring and dolomite porosity determination.
Mining Production and Mineral Processing
Evaluate and monitor mineral and ore properties to maximize a variety of mining processes and operations.
Rapid identification of mineral deposit alteration assemblages.
