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: A device (122) is described having an arrangement of optical elements comprising excitation light sources (101, 115) for generating individual light beams (102, 116) having different wavelengths for exciting a sample in such a way that light scattered back from the sample as a result of the excitation is made available to a Raman spectroscopic analysis. The device (122) has deflection devices (103, 117) associated with the individual light beams (102, 116) for deflecting the individual light beams (102, 116) onto a common light path, wherein the common light path has a same optical system (109) for focusing the light beams (102, 116).

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.

Abstract: The inventive waveguide structure comprises a first waveguide region having a constant first width adapted to guide electromagnetic waves mode sustainably along its longitudinal axis; a second waveguide region adapted to guide electromagnetic waves mode sustainably along its longitudinal axis, wherein the longitudinal axis of the first waveguide region and the longitudinal axis of the second waveguide region form a common longitudinal axis of the waveguide structure, wherein a first end face of the first waveguide region and a first end face of the second waveguide region are aligned with each other, the width of the first end face of the second waveguide region corresponding to the first width, and the width of the second waveguide region along its longitudinal axis widens from the first end face to a second end face to a second width greater than the first width.
