Optical System
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 14 mm or 8 mm and transported under rough vacuum through a KBr (or polyethylene) window and into the nitrogen-purged, Bruker endstation.

Experimental Apparatus
Bruker Vertex 80v Step-Scan FTIR equipped with KBr beamsplitter and an internal DTGS-KBr detector.

Bruker Hyperion 3000 IR microscope equipped with 15x, 36x, and 74x transmission/reflection IR objectives. "View-thru" capability allow simultaneous sample viewing and IR data collection. Two glass objectives (4X and 20X plan) for visual inspection. DIC and fluorescence microscopy capabilities. IR and visible polarizers.

Automated X-Y scanning stage for spectroscopic mapping. Includes video image capture of sample specimen. Step resolution of 1 micron.

128x128 FPA and small area MCT-A detectors

Computer System Hardware & Software
Intel Pentium VI, 2.0 GHz computer running Windows XP; 2.0 GB RAM, 200 GB hard disk, 17" flat panel monitor; Bruker OPUS software; HP LaserJet 1100 (B&W) printer for hardcopy output. Data can be stored via USB jump drive or external hard drive.
