Abstract

The invention is a borehole instrument system comprising a housing (1) in a borehole (B), the housing (1) provided with an optical window (6, 61) for guiding a low-energy laser beam (L) induced in a laser (5) towards a borehole wall (w), and a lens (6, 62) for collecting Raman scattered light (R) induced by the laser beam (L) and transmitting the Raman scattered light (R) to a Raman detector (8), said Raman scattered light for use for identifying at least one mineral of said borehole wall.
