Control System Development for a Raman Spectrometer Using Microcontroller Technology

An electronic control system has been developed for a Raman spectrometer by using electronics based on microcontrollertechnology. With these microcontrollers it is possible to emulate control circuitry capable of performing complex tasks, suchas the monochromator step motor control and the photomultiplier pulse count required in the Raman spectroscopy process.This approach could be used to give new life to valuable scientific instruments and tools. The Raman spectrometer controlbuilt is now fully functional and compatible with Windows 7. Raman spectra from well-known materials are presented tocompare results and in order to confirm the proper operation of the developed control system.
