Abstract:
The conversion of single-beam monochromators to double-beam microspectrometers is described. The principal advantage of the present system over others used is a great improvement in the long-term stability of the electronics; other advantages include simplicity, compactness, and complete freedom from beats due to mains frequency pickup. The system has been designed for use, in conjunction with a polarizer, for the examination of fibers, small crystals, and small areas of oriented biological macromolecules as well as for microsamples.

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...
