OPTICAL CONFIGURATION

Beamline Optical System

A two-mirror system (M1 and M2) collect and re-image the synchrotron infrared source at a point just ourside 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 a bare aluminum reflective coating.  The ellipsoidal mirror focuses the beam through a 10mm aperture wedged diamond window (~350 microns thick).  Delivered spectral range extends from approximately 10 cm^-1 to beyond 40,000 cm^-1.  Beam is then collimated (aluminized off-axis paraboloid) to the IR spectrometer.

Experimental Apparatus

Bruker IFS 66v vacuum interferometer with step-scan. Beamsplitters and detectors for far IR (bolometer, 20 to 700 cm^-1), mid & near IR (Si:B and InSb, 350 cm^-1to 11,000 cm^-1) and visible (Si, up to 25,000 cm^-1).

Computer System Hardware and Software

Bruker's OPUS running under OS/2 on Intel Pentium based PC.
