Light-emitting diode based shifted-excitation Raman difference spectroscopy (LED-SERDS)

Abstract

Fluorescence interference is a common problem in Raman spectroscopy. A low-cost solution using shifted-excitation Raman difference spectroscopy (SERDS) with a light-emitting diode (LED) is presented. A conventional dielectric bandpass filter is employed to narrow the spectral bandwidth of the LED radiation and to stabilize its wavelength. Moreover, angle-tuning of the filter allows the wavelength to be controlled and shifted in order to record SERDS spectra.
