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: A hybrid image-pupil optical reformatter and method for optional use with a spectrometer is disclosed, which performs beam slicing in pupil space and stacks replicas of the input source generated from the pupil beam slices in image space. The optical reformatter comprises a collimator which receives an input light and produces a collimated beam; a first optical element which receives the collimated beam, redirects portions of the collimated beam back toward the collimator as reimaged beams and permits portions of the collimated beam to pass; a second optical element which receives the reimaging beams and redirects the reimaging beams back toward the collimator and the first optical element; to form an output beam comprising the portions of the collimated beams that are not redirected toward the collimator by the first optical element. Also disclosed is the use of the reformatter for reformatting the input light of a spectrometer system, and the use of the reformatter as part of a spectrometer device.

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).
