Patent number: 10481084Abstract: A spectroscopy system and method in which the optical path following the interferometer includes a Jacquinot stop having an aperture disposed substantially at its focal point. The Jacquinot stop includes a reflective surface substantially non-orthogonal to the longitudinal axis of the path and facing the source of the IR signal containing an interferogram. The aperture passes an inner portion of the incident IR signal, while the reflective surface reflects an outer portion. The reflected outer portion of the incident IR signal, which contains erroneous spectral information due to inherent flaws in the interferometer optics, is thereby effectively removed from the original incident IR signal ultimately used to irradiate the sample, and yet still be made available for use in monitoring background spectra of the sampling optics.Type: GrantFiled: July 13, 2018Date of Patent: November 19, 2019Assignee: Thermo Electron Scientific Instruments LLCInventor: John Magie Coffin

Patent number: 9952138Abstract: The present invention is thus directed to an automated system and method of varying the optical path length in a sample that a light from a spectrophotometer must travel through. Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Such a methodology and system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.Type: GrantFiled: October 9, 2015Date of Patent: April 24, 2018Assignee: Thermo Electron Scientific Instruments LLCInventors: John Magie Coffin, Damian W.

Patent number: 9952139Abstract: An apparatus includes a first pedestal surface coupled to i) a swing arm and to ii) a light source. The apparatus further includes a magnet, a base plate, a mechanical stop coupled to the base plate, and a second pedestal surface mechanically coupled to said base plate and configured to receive a liquid sample, said second pedestal surface being coupled to a spectrometer. The apparatus further includes a magnetic flux sensor located between north and south magnetic flux fields of the magnet such that the magnetic flux reaching the sensor while the mechanical stop is in physical contact with the swing arm provides a linear range of output of the magnetic flux sensor, and a processor adapted to calibrate the point for minimum optical path length using a threshold magnetic flux field emitted from the magnet and detected by the magnetic flux sensor.Type: GrantFiled: September 12, 2016Date of Patent: April 24, 2018Assignee: Thermo Electron Scientific Instruments LLCInventors: Damian W.

Patent number: 9383308Abstract: MCR provided estimated pure component time series spectra as extracted from infrared or other spectroscopy is capable of being compared to spectra in a reference library to find the best matches. The best match spectra can then each in turn be combined with the reference spectra, with the combinations also being screened for best matches versus any one of the estimated pure component time series spectra. These resulting best matches can then also undergo the foregoing combination and comparison steps. The process can repeat in this manner in an unbounded fashion if desired until an appropriate stopping point is reached, for example, when a desired number of best matches are identified, when some predetermined number of iterations has been performed, etc. This methodology is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.Type: GrantFiled: October 17, 2012Date of Patent: July 5, 2016Assignee: Thermo Electron Scientific Instruments LLCInventors: Michael S.

Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Moreover, the system utilizes configured wedge shaped windows to best minimize the reflections of light which cause periodic variation in transmission at different wave lengths (commonly described as “channel spectra”). Such a system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.Type: GrantFiled: September 4, 2015Date of Patent: July 5, 2016Assignee: Thermo Electron Scientific Instruments LLCInventor: John Magie Coffin
