    Abstract: Raman spectroscopy systems include an analyte, a radiation source configured to emit incident radiation having a wavelength, and a detector that is capable of detecting only radiation having wavelengths within a detectable range that includes at least one wavelength corresponding to hyper Raman scattered radiation scattered by the analyte. The wavelength of the incident radiation is outside the detectable range. In particular systems, all wavelengths of radiation that are scattered in the direction of the detector impinge on the detector. Raman spectroscopy methods include providing an analyte and irradiating the analyte with incident radiation having a wavelength, providing a detector capable of detecting only wavelengths of radiation within a detectable range that does not include the wavelength of the incident radiation, and detecting Raman scattered radiation scattered by the analyte. A continuous path free of radiation filters may be provided between the analyte and the detector.
