Application of a microcomputer to optical spectroscopy
Abstract:
A low-cost microcomputer-based scanning instrument controller is described which has been used with both a Fabry-Perot interferometer and a grating monochromator. The system is based on a commercially available single-board computer. The controller can be used in either a passive mode, where it functions as a replacement for a multichannel analyzer, or in an active-control mode. Only the read-only memory held program need be changed to adapt the device to a scanning instrument in either mode. Interface circuitry and typical programs are described.

Applications of IR Spectroscopy: Overview
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...
