Demonstrated Wavelength Portability of Raman Reference Data for Explosives and Chemical Detection
Figure 1
Hg-line spectrum used for interferometer calibration. Several lines are used to calibrate the absolute wavelength response of the interferometer. The Raman laser frequency ~9397 cm−1 is bracketed by the Hg lines. The inset shows the linewidth (FWHM) of one of the Hg lines.
