Abstract: New and improved optical system for use in apparatus for the automatic, simultaneous multielement analysis of samples by atomic spectroscopy which include a plurality of radiation sources effective to emit radiation of different wavelengths for the irradiation of a sample burner flame are provided, and comprise radiation source optic means including a plurality of toroidal mirrors for reflecting the radiation from said plurality of radiation sources and focusing said radiation substantially at the same volume of said sample burner flame for irradiation thereof, and detector means optics, including spaced primary and secondary mirrors for observing substantially only said irradiated sample burner flame volume and focusing substantially only the radiation therefrom at the radiation detector.
