Abstract: A tool for measuring properties of a formation fluid downhole within a wellbore is described. The tool comprises a port for obtaining a sample of fluid downhole and a spectroscope. The spectroscope includes an adaptive optical element, a light source, and at least two detectors. The adaptive optical element is capable of directing a first wavelength band along a first light path and a second wavelength band along a second light path when both said bands are simultaneously incident thereon. The spectrum of the light source is spectrally dispersed across the adaptive optical element in such a way that a first wavelength band is directed along the first light path, through the sample, and to one of the detectors, and a second wavelength band is directed along the second light path to a second of said at least two detectors.
