Emission and transmission optical spectrometer

摘要

A novel emission and transmission optical spectrometer is introduced herein, which is capable of optically interrogating solid or liquid samples of organic, inorganic or polymeric chemistry, for pharmaceutical research, forensic and liquid analyses, used for identification, purity check, and/or structural study of chemicals. The beneficial aspects of the system are a single sample compartment as confined within the walls of the spectrometer housing, a more compact accessory, and the capability of making both emission (e.g., Raman and Fluorescence) and Infrared (IR, NIR) transmission measurements at designed sample points.

主权项

1. An optical instrument for use in transmission and emission spectroscopy, comprising:
a spectrometer housing having a single sample compartment disposed within the walls of said spectrometer housing; an accessory coupled to said single sample compartment, said accessory further comprising an excitation source configured to generate emission from a sample coupled to an emission sample platform; a transmission sample platform offset from said emission sample platform so as to be configured for infrared (IR) transmission operation; an infrared (IR) source of radiation; an interferometer adapted along a designed optical path so as to modulate either said emission or the light received from said infrared (IR) source of radiation; a first optical element configured to direct to an emission detector, the emission received along said designed optical path or to direct said infrared (IR) source of light along said designed optical path; and a second optical element configured to receive directed infrared (IR) light transmitted therethrough a sample coupled to said transmission sample platform and further adapted to direct said infrared (IR) light transmitted therethrough to one or more infrared (IR) detectors.
