OreXpress Field Portable Spectrometer
For Mineral Identification and Analysis
SPECTRAL EVOLUTION OreXpress Spectrometers are ideally suited for mining exploration, mineral identification, and mining production. These spectrometers cover the UV/VIS/NIR spectra using three photodiode arrays with no moving parts.
Advantages of OreXpress Field Portable Spectrometer
- High signal-to-noise ratio for better reflectance values.
- Fast start-up and use, with no optimization step required to start scanning or between scans.
- Collect target data with a single click.
- Mineral identification capabilities are built-in – use our EZ-ID software, compare scans versus existing libraries such as SpecMIN and USGS, or compare against your own custom libraries.
- Our library builder allows you to quickly build new libraries and add to existing libraries.
- Rugged handheld GETAC PS336 handheld microcomputer with a sunlight readable display includes an auto-focus digital camera, e-compass, altimeter, GPS and voice notes, as well as the ability to tag scans with pictures, notes GPS, etc.
- Ergonomic mineral contact probe and rugged metal clad fiber cable.
- Lightweight lithium-ion battery for power in the field.
