oreXpert
Spectral Evolution – NIR
Identify minerals in the field
The oreXpert™ NIR field spectrometer is engineered to deliver exceptional resolution while standing up to the demanding conditions of fieldwork. Its advanced optics make it possible to detect subtle spectral features, improving mineral unmixing and the identification of trace components.
The instrument’s performance is anchored by three high-density, thermoelectrically cooled photodiode arrays, ensuring outstanding stability and ultra-high resolution in every measurement.
The oreXpert™ stands as the highest-resolution field spectrometer available, giving geologists the ability to separate overlapping spectral features and identify critical vectoring minerals in mixed samples.
