Fast, reliable mineral identification and analysis in the field.

Overview

The oreXpress spectrometer brings full-range Near Infra-Red (NIR) analytical capability directly to fieldwork, optimising the workflow for mineral identification. It is highly durable, designed for remote and on-site use by geologists, and reduces the time required for core shack logging significantly.
