<p>An apparatus and method for combining NIR spectroscopy (20) with a rotatable specimen turntable (16) for measuring major constituents of harvested product (26) in real time. The monochromator includes a fixed diffraction grating (38) and a photodiode collector (40) comprised of a plurality of photodiodes (54). A radiation source (44) irradiates a product sample rotating on the turntable, and the reflected radiation is transmitted to the diffraction grating. By analyzing the intensities and wavelengths of the reflected radiation at the photodiode collector, the presence and amount of constituents or characteristics of the harvested product can be determined.</p> |
