摘要：
BESO (Bochum Echelle Spectrograph for OCA) is a high-resolution echelle spectrograph which has been built by Ruhr-Universitaet, Bochum and Landessternwarte Heidelberg. It is fiber-coupled to the 1.5m Hexapod-Telescope at the Observatorio Cerro Arinazones (OCA), Chile. The first light spectra show that the resolution of 48.000 over a spectral range from 370 nm to 840 nm has been achieved. A alignment by design approach has been followed to assemble the fiber-head optics at the telescope side of fiber coupled instrument.
