1. A multi-fibre optical probe for in-line spectroscopic monitoring of high concentration mediums comprising:
at least one light detection fibre wherein each light detection fibre is configured to receive light at a light receiving end, and
at least two illumination fibres configured to emit light from a light emitting end; wherein
the number of illumination fibres is equal to or greater than the number of light detection fibres, and
the light emitting ends of each of the illumination fibres are each independently positioned 50 microns or less from the light receiving end of at least one light detection fibre;
wherein the multi-fibre optical probe does not comprise a window or other structure covering and/or in between and/or in front of any of the light emitting ends of the illumination fibres and any of the light receiving ends of the light detection fibres.
