Synchrotron infrared microspectroscopy imaging using a multi-element detector (IRMSI-MED) for diffraction-limited chemical imaging

University of Wisconsin—Milwaukee is designing and installing a mid-infrared beamline, IRMSI-MED, that will extract 320(h)×25(v) mrad2 from a bending magnet (BM) at the Synchrotron Radiation Center. The BM radiation, collected with 12 toroidal mirrors and collimated with paraboloidal mirrors, illuminates a spot of 60×40 μm2 at the sample plane of a commercial IR microscope. The microscope is equipped with a multi-element detector (MED) that will provide the opportunity to obtain chemical images with diffraction-limited resolution of the illuminated area in under a minute.
