Spectral Evolution NIR/SWIR Spectrometers for Mineral Mapping

Technology: UV-Vis-NIR/SWIR Reflectance Spectroscopy (350–2500 nm)
Manufacturer: Spectral Evolution (USA)
Integrated Solution Provider: Geospectra 

Fast, Accurate Mineral Identification in the Field

The Spectral Evolution oreXpress™, oreXplorer™, and oreXpert™ are field-portable UV-Vis-NIR/SWIR spectrometers purpose-built for geological and mining exploration. Combining 350–2500 nm full-range reflectance with EZ-ID™ mineral identification software, these instruments deliver instant, non-destructive mineral characterization anywhere—from outcrop to core shed.

With high signal-to-noise ratios, no moving optical parts, and battery-operated portability, Spectral Evolution spectrometers give geologists the power to collect more scans, cover more ground, and obtain reliable mineral alteration data in seconds. Integrated with FieldScan ONE™, they provide full QA/QC traceability and cloud-linked data workflows for modern exploration programs.

Application:

Rapid, non-destructive mineral identification and alteration mapping for mining exploration, geological research, and environmental studies.

Solution Highlights:

• Full-spectrum coverage (350–2500 nm) in a single scan.
• High resolution and signal-to-noise optimized for field environments.
• Instant start-up: no warm-up or optimization step between scans.
• Fast spectral collection (100 ms per scan) for high-volume field data.
• Battery-operated portability—up to 5 hours of continuous use.
• No moving optical components ensures reliability and stability.
• Rugged design with reinforced fiber-optic cable and quick-disconnect connectors.
• EZ-ID™ mineral library matching for immediate identification of clays, carbonates, oxides, sulfates, and hydroxyl-bearing minerals.
• DARWin™ SP software for automatic data acquisition, QA/QC tracking, and integration with FieldScan ONE™.
• Optional contact probe, fiber reflectance probe, or field tablet for fully mobile workflows.

Ideal for:

• Mining and mineral exploration
• Alteration mapping and vectoring to ore deposits
• Core logging and geometallurgical modeling
• Ground truthing for remote sensing
• Environmental and soil spectral studies
• Oil, gas, and energy exploration

Key Benefits:

• Field-Ready: Lightweight, rugged design for core sheds, field tents, and mobile labs.

• Speed: Acquire hundreds of scans per hour for statistically robust data.

• Accuracy: 1 nm sampling and ± 0.5 nm wavelength accuracy ensure reproducible spectra.

• Stability: Fixed optics and sealed detectors maintain alignment and calibration.

• Integration: Compatible with Vanta XRF, FENIX XRD, and FieldScan ONE™ for unified mineralogical and elemental datasets.

Model Overview:

All models deliver 1 nm data output with 2151 spectral channels, 0.1 nm reproducibility, and DARWin™ SP software compatibility.
