Abstract
The technology provides a spectroscopy system having a fringe tilted grating that varies a refractive index to diffract light. The diffracting mechanism may be formed by modulating a refractive index to produce fringe planes that are oriented relative to each other through a depth of the grating material The spectroscopy system includes a detector that converts optical signals into electrical signals to render spectral data. The spectroscopy system employs the fringe tilted grating to minimize fictitious Raman peaks that correspond to a fluorescence response signature.
