Scanning UV Raman Spectrometer:
Design: Two Czerny-Turner scanning spectrographs, with rotating triple grating each.
Excitation Spectral Range: tunable over 210 to 400 nm.
Spectral Resolution: 10 cm^-1 over the entire range.
Broad Raman shift: From 700 to 1,800 cm^-1.
Beam dump for excitation laser (designed to direct laser beam to dump at all excitation wavelength).
Stray light rejection: better than 1:1E6, and better than 1:1E8 for excitation laser in +1,0,-1 diffraction orders.
Self calibration using the tunable excitation laser.
Applications: Chem/bio hazardous materials. |
