Instrument consists of a combination of Fourier infrared spectrometer with infrared microscope. In the spectrometer, one can perform transmission and reflection experiments on samples dimension of roughly 1 mm2 and more in the full frequency range offered by the spectrometer, 30–14 000 cm-1. The microscope is used for measurements of either small or spatially inhomogeneous samples essentially down to the diffraction limit in the far field, it means roughly 3 at 3000 cm-1. The frequency range is however limited by the microscope detectors to 600–6000 cm-1. The highlight of this microscope is the focal plane array (FPA) detector that allows simultaneous recording of 128×128 matrix of spectra in the frequency range 900–5000 cm-1.
