Abstract :
We show the concept of a dispersive mid-IR spectrometer to record single-shot spectra in the μs-time range with a high SNR. A linear FPA-detector is combined with a dispersive Féry-prism arrangement. In addition, diffraction limited infrared synchrotron radiation is used to optimally illuminate the entrance aperture of the spectrometer.
