FEROS instrument is a state-of-the-art bench-mounted, high-resolution,
Environmentally controlled, astronomical Échelle spectrograph. It is
opertated at the European Southern Observatory (ESO) in La Silla, Chile,
one of the best astronomical sites in the world.
The high efficiency (~20%), large wavelength range (the
complete optical spectral region in one exposure) and high resolution
(R=48000) makes possible a large variety of stellar and
extra-galactic spectroscopic observation programs requiring high
spectral stability can be carried out.
