    Abstract

    The Ultra-High-Resolution Facility (UHRF) has been commissioned at the coudé focus of the Anglo-Australian Telescope (AAT), and provides a resolving power of R≈106. This is the highest spectral resolution ever obtained by an optical astronomical spectrograph, and is intended mainly for astrophysical studies of cool interstellar clouds. This paper describes the development of this ambitious project, which includes diffraction-limited optical components, very tight specification for the optical configuration, and a new type of image slicer which allows ultra-high-resolution work towards faint stars. Astrophysical results from the first observing runs are presented to demonstrate the performance in terms of both resolution and throughput.
