Tübingen Echelle Spectrograph

The Tübingen Echelle Spectrograph (TUES), designed and managed at the University of Tübingen, flew on the Orbiting and Retrievable Far and Extreme Ultraviolet Spectrograph (ORFEUS)-SPAS II space shuttle mission in 1996, returning spectra in the 900 Å to 1400 Å wavelength range. The instrument was designed to achieve a spectral resolution of $\lambda$/$\Delta$$\lambda$=10000 when used with an entrance aperture of 10" diameter. During the 17.7 day flight, TUES returned 239 spectra of 62 targets.
