Abstract:
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.
