Abstract

In a unique way, IRENI (Infrared environmental Imaging), operated at the Synchrotron Radiation Center in Madison, combines IR spectroscopy and IR imaging, revealing the chemical morphology of a sample. Most storage ring based IR confocal microscopes have to overcome a trade-off between spatial resolution versus signal-to-noise ratio (SNR). For IRENI, this problem has been addressed by introducing a beam-matrix that is comprised of 3x4 IR-beams, generated from the fan of a bending magnet extracted over a range of 320x27mrad² by employing a set of suitable mirrors, see Fig. 1 [1].
