InPhotonics: RS2000 high resolution Raman spectrometer.

RS2000 High Resolution Raman Spectrometer

High resolution RS2000 system provides research-grade performance in a rugged spectrometer design. 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. The lens based optics are matched to a fiber optic input, providing 1:1 imaging at the focal plane and negating the need for entrance slits.

Combined with the RamanProbe^TM for remote sampling, the RS2000 is the ideal Raman spectrometer for difficult environments where portability and insensitivity to vibration are required. The RS2000 is also perfect for applications requiring high resolving power and complete spectral range coverage.

The RS2000 is available in two standard configurations with either a 785 nm or a 532 nm excitation laser. The system includes InPhotonics' data acquisition package and GRAMS AI manipulation software (from Thermo Electron Instruments, Inc.) operating on a standard PC data station.
