Abstract: Methods and systems are described for performing spectroscopic measurement of at least one analyte of interest in an inhomogeneous sample using a spectroscopic system. This generally involves generating and aiming an illumination beam which forms a focal region having focal region size S upon a surface or within a volume of the sample where there is relative motion between the sample and the focal region at a relative speed V; selecting a desired ratio between an exposure time E for a detector of the spectroscopic system and a transit time T for a particle of the at least one analyte of interest to traverse the focal region; acquiring one or more spectral data sets corresponding to spectra for a region of the sample within the focal region; and analyzing the one or more spectral data sets to generate one or more corresponding analytical results.

Abstract: Various embodiments are provided herein for a Raman analyzer system and associated method of analyzing a chemical process including a supercritical fluid extraction process or a solvent extraction process using a Raman analyzer system where the method involves generating light stimuli and providing the light stimuli to a sample of the chemical process; collecting scattered light from the sample; filtering the scattered light using one or more selected optical filters for selectively attenuating one or more wavelength sections for Raman analysis; detecting the filtered light; and generating one or more filtered Raman spectra of the detected light.

Abstract: Various embodiments are provided herein for an optical spectroscopy probe which generally includes a probe head having optical elements for coupling to an excitation fiber for receiving laser energy therefrom and generating a collimated excitation light beam; and a sample optic adjacent to the probe head, the sample optic having at least one optical element with two non-parallel surfaces to receive the collimated excitation light beam, to transmit the collimated excitation light beam to a sample, and to collect at least one afocal returning scattered light beam that is reflected from the sample.

Abstract: Sample optic assemblies are described that may have at least one optical element that is positioned and has one or more surfaces shaped to focus separate sections of a collimated excitation light beam to: (a) create at least one focal point or at least one focal line at one or more portions of a surface or an interior of a sample while compensating for optical aberrations that are created by an optical window or a transparent container that is adjacent the sample to reduce the size of and/or sharpen the at least one focal spot or the at least one focal line; (b) to create a plurality of focal spots, an array of discrete focal spots, at least one focal line, or at least one focal circle, at one or more portions of a surface or an interior of the sample or (c) to achieve (a) and (b).
