A Fourier transform Raman spectrometer with visible laser excitation

open access: yes, 2014
We present the development and performance of a Fourier transformation (FT) based Raman spectrometer working with visible laser (532 nm) excitation. It is generally thought that FT-Raman spectrometers are not viable in the visible range where shot-noise ...
