Abstract
UVES is a dual beam echelle spectrograph installed at the Nasmyth focus of the UT2 telescope of the ESO VLT since October 1999. It can reach a resolution of 80000 and 115000 in the blue and red arm, respectively. The instrument is characterized by great stability and high efficiency. The smooth operation of both the new telescope and instrument has lead to a remarkable number of highly interesting scientific observations during commissioning. Examples of scientific work on these data are presented to illustrate the unique UV efficiency, the resolving power and high S/N capability and far red efficiency.
