Abstract
A spectroscopic system for measuring content of a constituent in a sample of a natural product is provided. The spectroscopic system includes a source for electromagnetic (EM) radiation and an absorbance filter for filtering EM radiation received from the source, where the absorbance filter transmits EM radiation of predetermined wavelengths solely by the absorbance characteristics of the filter material. The spectroscopic system also includes a sample holder which is positioned adjacent the source with the absorbance filter positioned therebetween such that only EM radiation of predetermined wavelengths are incident on the sample, a detector for generating an electrical signal indicative of the EM radiation resulting from interaction of the incident EM radiation of predetermined wavelengths with the sample of the natural product and a processing circuit, preferably a microprocessor with memory, responsive to the resulting EM radiation indicative signal for determining the content of the constituent in the sample of the natural product.
