High Resolution Atomic Spectroscopy

A large part of the experimental program of the Atomic Spectroscopy Group centers around our high-resolution spectrometers. Our collection of "classical" grating spectrometers and "modern" Fourier transform and laser spectrometers allow us to perform wavelength measurements of nearly unparalleled accuracy.

Classical Spectroscopy

Several High-Resolution Instruments, including:
10.7 m Normal Incidence Spectrograph
10.7 m Grazing Incidence Spectrograph
Czerny-Turner Spectrograph

Spectral Coverage: 300 nm to 18,000 nm
Resolution: 0.0025 cm-1
Uncertainty: ±0.0001 cm-1
Computerized scan control and data acquisition control
