OreXpress Field Portable Spectroradiometer

Description

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.

 

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
DARWin SP Data Acquisition software automatically saves scans as ASCII files – no hours of pre-processing to use with 3rd party software
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

Applications of OreXpress  Spectrometer

Geologists and exploration managers can identify minerals associated with gold, silver, iron, copper, diamonds, aluminum, uranium, and more across a range of deposit types, including epithermals, porphyries, kimberlites, carbonate hosted base metals, shear veins, skarns, and disseminated gold systems.
