  • Patent number: 6137108
    Abstract: A probe for a spectrometer has a slot for receiving a sample, an illuminating fiber optic bundle directing light to the sample in the slot, and first and second collecting fiber optic bundles transmitting light from the sample to the spectrometer, wherein the first collection fiber optic bundle is positioned to optimize the collection of transmitted light without scattering through the sample, and the second collection fiber optic bundle is positioned to optimize the collection of light diffusely reflected from the sample. In one embodiment, the first collection bundle is arranged in an annulus around the illuminating bundle, and the second collection bundle is arranged in an annulus around the first collection bundle. In a second embodiment, the second collection bundle is arranged in an annulus around the illuminating bundle, and the first collection bundle terminates in an interface with the sample located across the slot from the illuminating bundle and the second collection bundle.
