Description:
The RS2000 is the first Raman spectrometer to offer both high resolution and full spectral range capabilities in a system without moving parts or throughput-limiting slits. Unique to the system is an echelle spectrograph that offers light dispersion in two dimensions to fully exploit the CCD detector area. The result is better than 1 cm-1 spectral resolution from 200 - 3500 cm-1 (Raman shift). In fact, the spectrometer can provide this range and resolution without switching grating positions. As a matter of fact, the lens-based optics are matched to a fiber optic input, providing 1:1 imaging at the focal plane and negating the need for an entrance slit.

As for the optical design, the RS2000 (visible) echelle spectrograph comes with an aluminium-coated grating and visible prism for cross dispersion which in fixed configuration, employs no spectral slits. Conversely, the RS2000 (near-IR) echelle spectrograph comes with gold-coated grating and near-IR prisms for cross dispersion which in fixed configuration does not employ spectral slits. As a versatile device, the RS2000 calibration method is configured in such a way that the fixed optics provide permanent calibration under typical operating conditions. This is because the intensity response correction is performed automatically through software.
