Abstract
Percentage concentrations of constituents or color components of a sample are determined using a spectral analyzer with a wide illumination spot size and detector. The analyzer irradiates the sample, picks up diffuse reflectance of individual wavelengths from the sample and spatially separates the diffuse reflectance into a response at individual wavelengths. The result is to simultaneously detect the intensities of the individual wavelengths in parallel from the sample being analyzed. Percentage constituents of a composite substance can be determined or, alternatively, the components of color in a sample can be determined by analyzing wavelengths of reflected light.
