<p>A fibre-optic probe (100) that minimizes the overlap between excitation light and collected light in an optical spectroscopy system is hereby disclosed. The fibre-optic probe comprises an illumination fibre (102) having a length and a tip proximal to a target, wherein the illumination fibre is configured to conduct light from a light source to the target. The fibre- optic probe also includes at least one collection fibre (104,106) having a slanted end proximal to the target, wherein the collection fibre is configured to conduct light away from the target. The illumination fibre is further configured to taper along at least part of its length towards the tip and the slanted end face of the at least one collection fibre faces the pencil-shaped tapered end face of the illumination fibre.</p>
