Field Portable NIR Spectrometers for Mineral Identification and Analysis in Mining Exploration
Field portable NIR spectrometers are invaluable tools for mineral identification and analysis in mining exploration. These spectrometers are designed to be compact and lightweight, allowing geologists and mining professionals to easily carry them to remote locations. NIR spectroscopy works by analysing the interaction between minerals and near-infrared light, providing information about mineral composition and concentration.
The SPECTRAL EVOLUTION difference
Spectral Evolution's field portable, battery-operated oreXpress, oreXplorer and oreXpert ultra-high resolution NIR spectrometers are designed for mineral identification in mining exploration.
- Rapid data/spectra collection in the field - allowing you to take more scans in less time
- High resolution in a field instrument
- High signal-to-noise ratio for improved reflectance values
- Fast start-up and use with no optimization step required between scans
- Sturdy construction for harsh field environments
- Reliable operation with no moving optics and a robust fiber optic cable with quick-disconnect
- Rugged and reliable mineral contact probes for single click field measurements to measure outcrops, cores and chip trays
COMPARISON OF THE SPECTRAL EVOLUTION PORTABLE SPECTROMETERS
Specifically designed for fieldwork, Spectral Evolution spectrometers utilize all solid-state photodiode array detectors with no moving optical parts on a rugged chassis to ensure toughness and provide excellent stability and repeatability of measurement in the field.
- Full Spectral Range of 350-2500nm
- 3 Photodiode Arrays
- No moving parts for greater reliablity
- Automatic optimization of dark current and exposure with every scan
- User-replaceable metal-clad fiber optic cable
- Lightweight and compact
The oreXplorer can be used with either of two mineral contact probes: our standard contact probe with a 10mm spot size or our Miniprobe with a 3mm spot size.
The oreXplorer provides high resolution and high sensitivity for mineral exploration, mineral identification and mineral mapping applications for in situ field measurements. It includes an enhanced 1024 element silicon array and improved spectral resolution
