High resolution Fourier transform spectrometer (0.005 cm(-1)) for the 0.6-100-microm spectral range
Abstract:
The construction of a high resolution (0.005-cm(-1)) Michelson interferometer with cat's eye retroreflectors is described in some detail. The instrument line shape function of the Fourier spectrometer at 0.63 microm agrees with theory at 0.02-cm(-1) resolution. Absorption spectra of gases have been measured using a 40-m White cell. Infrared luminescence spectra have also been measured using a calcium fluoride crystal doped with divalent dysprosium, cooled to 4.2 K, and excited with radiation from a quartz halogen lamp.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
