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 aperture wedged diamond window (~350 microns thick). Delivered spectral range extends from approximately 10 cm-1 to beyond 40,000 cm-1. The infrared is then collimated to a diameter of 14mm and transported under rough vacuum into the Bruker Vertex 80v vacuum spectrometer, through the exit port (KBr window) into the nitrogen-purged Hyperion 3000 IR Microscope endstation.
