A two-mirror system (M1 and M2) collects and re-images the synchrotron infrared source at a point just outside of the storage ring's UHV. M1 is a water-cooled plane mirror made from silicon with a gold reflective coating. M2 is a glass ellipsoid with an aluminum reflective coating. The ellipsoidal mirror focuses the beam through an 11mm clear aperture wedged diamond window (~350 microns thick). Delivered spectral range extends from approximately 20 cm-1 to beyond 40,000 cm-1. The infrared is then collimated to a diameter of 14 mm and transported under rough vacuum through either a CsI or polyethylene window and into the nitrogen-purged, Spectra Tech Irus endstation.
Spectra Tech Irus IR microscope equipped with both 15X (0.57NA) and 32x (0.65NA) infrared objectives, 10X (0.71NA) condenser, Si beamsplitter, and choice of MCT, Ge:Cu, or bolometer detector. Automated X-Y scanning stage for spectroscopic mapping. Includes video image capture of sample specimen. Minimum step size of 1 micron.
