Abstract: Optical systems and methods for spectroscopy are described. The optical system may be particularly suitable for Raman spectroscopy and includes a multispectral excitation source, designed to emit monochromatic excitation radiation successively at at least two different excitation wavelengths along a common beam axis; an elongated flow volume with a longitudinal axis, designed to direct a particle flow along the longitudinal axis; an excitation beam path, designed to irradiate the monochromatic excitation radiation into the flow volume at a first position and the second position that are located in the flow volume and the first position is spaced apart from the second position; and a detection device, designed to wavelength-selectively filter and detect a portion of a radiation scattered from the first position at a first filter wavelength and to wavelength-selectively filter and detect a portion of a radiation scattered from the second position at a second filter wavelength.

Abstract: Raman spectroscopy methods and devices are disclosed.The method includes irradiation of excitation radiation onto a sample to be examined. The sample is irradiated with a first excitation radiation of a first excitation wavelength and a different second excitation radiation of a second excitation wavelength. The first excitation radiation scattered by the sample is wavelength-selective filtered by means of a passive filter element. A transmitted filter wavelength of the filter element differs from at least the first excitation wavelength and the second excitation wavelength. A first intensity is determined through a single-channel detector assigned to the filter wavelength from the first excitation radiation scattered and filtered by the sample. Additionally, the filter element wavelength-selective filters the second excitation radiation scattered by the sample. A second intensity is determined through the single-channel detector assigned to the filter wavelength from the second excitation radiation scattered and filtered by the sample.
