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.
