Abstract Atomic spectroscopy is an important evidence for the study of atomic structure, but it is very difficult to design an intuitive classroom experiment in teaching. This paper designed a self-made spectroscope and transformed it into a digital beam splitter, the fiber optic spectrometer was also introduced, based on these instruments the spectrum of sunlight, sodium and strontium was analyzed. Then this paper introduced atomic structure teaching supported by experimental design.
