The program in atomic spectroscopy at NIST provides accurate reference data on spectral lines and energy levels for a wide variety of important applications. Our spectrometers, among the most powerful of their type in the world, can record spectra from the extreme ultraviolet (wavelength = 1 nm) to the infrared (wavelength = 18 000 nm) and include a 10.7 m normal-incidence spectrograph, a 10.7 m grazing incidence spectrograph, a high resolution Fourier transform spectrometer, and a high accuracy Fabry-Pérot laser wavemeter. The Data Center compiles wavelengths, energy levels, and transition probabilities that support numerous applications in industry and the scientific community.
The Atomic Spectroscopy Group at NIST has a long history of contributions to optical science and metrology. Please read Joseph Reader's report on the group's history for more information.
