In order to improve fluorescence measurements, there is provided an apparatus and, a method and a computer program for optical analysis of an associated tissue sample, the apparatus comprising a spectrometer comprising an optical detector, a light source, a first light emitter 219 arranged for emitting photons into the associated tissue sample, a first light collector 221 arranged for receiving photons from the associated tissue sample, a second light emitter 223, a second light collector 225, wherein a reflectance spectrum is obtained via the first light emitter 219 and collector 221 and a fluorescence spectrum is obtained via the second light emitter 223 and collector 225, and where a first distance d1 between the first light emitter and collector is larger than a second distance d2 between the second light emitter and collector. By combining the data thus obtained, an intrinsic fluorescence spectrum may be obtained. |
