摘要：

UVES is a dual beam echelle spectrograph installed at the Nasmyth focus of the UT2 telescope (Kueyen) of the ESO VLT since October 1999. It can reach a resolution of 80000 and 115000 in the blue (300-500nm) and red (420-10050 nm) arm, respectively. The instrument is characterized by great stability (similar to 100 mis after correction for temperature variations) and high efficiency (peaking at 25 % over the range 510-660 nm and >10% over 330-920nm).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 (detection of Beryllium at 313 nm in the spectrum of a metal poor star, studies of the Lyman alpha forest and metal lines down to z = 1.7), the resolving power and high S/N capability ( measurement of the lithium isotope ratio) and far red efficiency (abundance of the undepleted Zinc from the lambda 202.6 nm line in a DLA system at z = 3.4 toward a faint QSO).
