Abstract
A rapid near-infrared instrument for measuring constituents of nonhomogeneous samples is disclosed which alleviates the need for taking successive measurements of the sample, and repositioning the sample for each successive measurement, by providing a novel illumination system including a light pipe which transmits near-infrared energy to the sample at a plurality of substantially separate and independent location. This arrangement permits a plurality of subsample measurements to be taken simultaneously which enables accurate constituent measurements to be made quickly and easily.
