Fiber-coupling of Fourier Transform Spectrographs
S. Schäfer, P. Huke, D. Meyer +1
Fourier Transform Spectrographs (FTS) are versatile tools for measuring accurate, high resolution spectra. They are internally calibrated by a reference laser that runs in parallel…

Comparing the emission spectra of U and Th hollow cathode lamps and a new U line-list
L. F. Sarmiento, A. Reiners, P. Huke +4
Thorium hollow cathode lamps (HCLs) are used as frequency calibrators for many high resolution astronomical spectrographs, some of which aim for Doppler precision at the 1 m/s leve…
