WUVS Overview

The main task of the WUVS is to provide slitless, long-slit and echelle spectroscopy.

The WUVS spectrographs assembly includes the instruments VUVES, UVES, and LSS, which are being developed by Russia.  

Its design and construction is led by the Institute of Astronomy of the Russian Academy of Sciences (INASAN) in collaboration with several institutes of the Russian Academy of Sciences (RAS) and the Russian industry.
