    摘要: Certain configurations are described herein of an optical spectrometer and instruments including an optical spectrometer. In some instances, the optical spectrometer is configured to spatially separate provided wavelengths of light to permit detection or imaging of each provided wavelength of light. Improved sensitivities and detection limits may be achieved using the optical spectrometers described herein.

    摘要: Certain aspects, configurations, embodiments, and examples of a spectrometer with a compact design are described. In some implementations, the spectrometers according to the present disclosure may be used for optical emission spectroscopy (OES). The spectrometer architecture and imager described herein allows a single detector, compact, and high-throughput spectrometer. One or more aspects include an Echelle grating in a spectrometer that reuses optical surfaces to separate wavelengths of light. For example, in one or more aspects, a reflective triplet telescope acts as both a collimator and imager. By reusing optical components, the relative size of the spectrometer may be reduced.

    摘要: A flow cell for a fluorescence spectrometer includes a flow channel to receive a flow of a liquid sample, an excitation light entrance window to receive excitation light from a light source, and an emission light exit window to transmit fluorescent emission light from the liquid sample in the flow channel from the flow cell. The excitation light entrance window and/or emission light exit window includes a waveguide including: a waveguide core formed of a core material; and a cladding medium surrounding a portion of the waveguide core, wherein the cladding medium has a refractive index less than the refractive index of the core material. The waveguide defines a portion of the flow channel.
