1. A portable spectrometer system for analysis of a plant-based sample, comprising:

  • a portable enclosure;

    a stabilized light source mounted in the portable enclosure for delivering light to a plant-based sample, and light from the stabilized light source reflects from the plant-based sample;

    a plurality of fiber optics, each positioned to capture the reflected light from the plant-based sample then combined to produce a composite image with high contrast improving accuracy by eliminating errors due to sample surface roughness and the need for rotating the plant-based sample, said plurality of fiber optics each being arranged to receive light from the plant-based sample at a different angle than a second angle at which another of said plurality of fiber optics receives light, said angles being selected to enhance optical image contrast of said composite image; and

    a spectrometer configured to receive the high contrast image of reflected light from the fiber optics and convert the light image into an array of numeric values that represents a fingerprint of substances within the plant-based sample achieving the best accuracy without moving parts.
