1. An apparatus for analyzing a plant specimen, the apparatus comprising:
a housing assembly adapted to be in i) an open configuration adapted to receive a plant specimen, and ii) a closed configuration wherein ambient light is controlled therein;
a light source disposed in or coupled to the housing assembly, the light source adapted to shine light onto or through the plant specimen when the housing assembly is in the closed configuration;
a camera assembly coupled to the housing assembly, the camera assembly having an image sensor adapted to receive light from the plant specimen in i) a transmittance mode where light transmits through the plant specimen, or ii) a reflectance mode where light is reflected from the plant specimen, the image sensor adapted to thereby capture hyperspectral images of the plant specimen;
a specimen support adapted to support the plant specimen;
a drive member adapted to engage with the plant specimen, the drive member adapted to slidingly move the plant specimen along the specimen support surface; and
a specimen position sensor, adapted to provide a signal corresponding to position of the plant specimen as the plant specimen moves along the specimen support.
