Supercontinuum laser sources operating in the MIR spectral region now offer the potential to enrich the field of FTIR spectroscopy due to their distinctive properties, such as high-brightness, broadband spectral coverage and enhanced stability spectrometer. Light from an infrared source is split into two arms of Michelson interfer-ometer by a beam-splitter, a device that ideally, allows 50% of light to pass through to the movable mirror while re ecting the other 50% to the xed mirror. The beam that travels to the xed mirror is re ected and returns to the beam splitter again, after a total optical path length of 2L. The same happens. A.M. Othman, H.E. Kotb, Y. Sabry, et al.

We recently developed the world's first near-field IR photothermal microscope using synchrotron radiation (SR), which uniquely spans a spectral range from the near-IR to the far-IR/THz In infrared spectroscopy, samples exposed to infrared radiation selectively absorb radiation of specific wavelengths, causing a change of dipole moment (separation of positive and negative charges) of sample molecules. Consequently, the vibrational energy levels of sample molecules transfer from ground state to excited state. The frequency of the absorption peak is determined by the vibrational energy gap. The number of absorption peaks is related to the number of vibrational. Typical light sources used for IR absorption spectroscopy are robust, low-cost thermal blackbody emitters. Although their emission band covers the detection range of IR photodetectors, these sources have limited spectral brightness. Applications requiring bright and well-collimated beams, such as wide-field hyperspectral IR microscopy, use light produced by synchrotron light sources

Grating groove density and optimum blaze wavelengths range from. Fourier-transform spectroscopy offers several advantages over dispersive methods; these are especially important for effective use of the limited radiant power available from most infrared sources. Whereas a spectrometer samples only one small frequency range at any given instant and must scan these frequencies sequentially to produce a spectrum, an interferometer processes information from.
