Instrumentation for Raman Spectroscopy. Raman Monochromators and Polychromators. Michael J. Pelletier. Kaiser Optical Systems, Inc., Ann Arbor, MI, USA. 1 INTRODUCTION. Light collected from a sample needs to be processed in some way so that wavelength and intensity information can be extracted from the
persive technique. In Raman spectroscopy, however, the dispersive spectrometers ha- ve certain advantages over the interferometry. The largest manufacturers of FT-Raman spectrometers also produce dispersive Raman spectrometers. The dispersive instruments are signi cantly more sensitive (by a factor of ten to

INSTRUMENTATION TECHNIQUES OF. INFRARED AND RAMAN SPECTROSCOPY. Abstract. The experimental techniques of Fourier Transform infrared and Raman spectrographs and techniques involved in handling the samples are briefly explained. Advantages of Fourier. Transform spectrometers are also discussed.
This review gives an overview of the developments in the analysis of drugs of abuse and other illicit substances by Raman spectroscopy for forensic purpose. The review covers the brief overview of basic principle and instrumentation of Raman spectroscopy along with selected and recent applications for characterization of

Raman signal with frequencies ?0 ± ?m. Spontaneous Raman scattering is very weak and special measures should be taken to distinguish it from the predominant Rayleigh scattering. Instruments such as notch filters, tunable filters, laser stop apertures, double and triple spectrometric systems are used to reduce Rayleigh
In general terms the instrumentation required to undertake Raman spectroscopic studies is extremely simple. We require the following: 1. Some means of holding or containing the sample to be analysed.
