| OPTICAL CONFIGURATION |
|
Mirror System - Dipole bending magnet synchrotron source produces *continuum* spectral output.
Approximately 50% polarized (75% horizontal component, 25% vertical component). Light is collected by mirror system
using 90 mr by 90 mr extraction through 11mm diameter diamond window at f/11. Polarization is rotated 90 degrees
(predominantly vertical polarization) through FTIR spectrometer.
|
|
Experimental Apparatus - Standard spectrometer sample compartment. P-E style card holder.
External specimen chamber for relative transmittance or relative reflectance (no special provisions for absolute reference).
Heli-tran and Oxford OptiStat available only for Users with specific cryogenic experience (no support or detailed training provided by NSLS).
