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 spectrometer with an unobstructed, Schmidt reflector is described. The spectrometer may include a Schmidt corrector and a dispersive element as separate components. Alternatively, the Schmidt corrector and dispersive element may be combined into a single optical component. The spectrometer may further include a field-flattener lens.

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.
