    Abstract: The spectroscopy method involves feeding light from a stimulation light source (1) via a first optical fibre (2) to a fibre coupler (3) and from there via a second optical fibre (4) to a specimen (6). Fluorescent light emitted from particles in the specimen are fed via the second optical fibre back to the coupler and from there via a third optical fibre (8) to a detector (10). Alternatively, the light from the source can be fed to the specimen via a first optical fibre and fluorescent light from particles in the specimen passed via a second fibre to a detector, whereby the ends of the fibres facing the specimen are oriented w.r.t. each other so that emitted stimulation light passes to a specimen region from which fluorescent light will be detected.
