InPhotonics RS2000-3b-532 High Resolution VIS Raman Spectrometer w/ Andor DV420-OE CCD Camera. The RS2000 is the only Raman spectrometer to offer both high resolution and full spectral range capabilities in a system with no 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 ? 3900 cm-1 (Raman shift)*. No other system can provide this range and resolution without switching grating positions.532 nm excitation laser
