An interferometric rejection filter for Raman spectroscopy.
A three-mirror, multiple beam interferometer is described and analyzed in use as a rejection filter for elastically scattered light in a Raman scattering experiment. A prototype filter capable of attenuating laser source frequency light by a factor of 450 and passing 88% of Raman scattered signal is reported.
