Far Infrared Spectroscopy (Far-IR) 02B1-1


This beamline can provide IR light that is 100 – 1000 times brighter than standard laboratory IR sources, allowing the spectroscopic study of molecules with much higher precision and sensitivity; coupled to a Bruker IFS 125 HR with a 9-compartment-scanning arm, spectral resolution ? 0.001 cm-1 can be achieved.

The first collecting mirror is in a specially designed dipole vacuum chamber. Point to point focusing optics transfer the IR light first through a thin diamond window that separates UHV from rough vacuum and then into the high resolution Bruker spectrometer.
