Radiation enters the inlet port of the spectrometer through a sapphire window mounted on the interface plate. A tuning fork chopper cuts the incoming radiation at a specified frequency. The chopped radiation goes through some optics including a set of prisms that disperse the spectrum into its component wavelengths. The dispersed beam falls on a parabolic mirror that reflects it on to a detector array. The detector is a liner array with 256 Lead Selenide elements. A data acquisition board captures the signal from the detector. The spectrometer comes with a data acquisition board system with InfraSpec software installed. The InfraSpec software calculates the relative intensities corresponding to the voltage of each pixel, and plots it against the corresponding wavelength falling on each pixel. When referenced with calibrations obtained using a black body radiation source, the software provides the absolute values of radiation intensities recorded by the detector array.
