Abstract
The characteristics of a new double-pass double-monochromator spectrometer (DMDP2000) especially designed for low-frequency light-scattering studies are reported. Preliminary spectra are presented to show the high resolving power achieved with a free spectral range of 2000 cm-1, as well as the high luminosity, contrast and stability. Spectra obtained with a single-pass Fabry-Perot interferometer are also shown for comparison.Keywords
