The high-resolution FIbre-fed Echelle Spectrograph (FIES) is a cross-dispersed high-resolution echelle spectrograph at the Nordic Optical Telescope (NOT). The entire spectral range of 370-730nm is covered without gaps in a single, fixed setting.

The European Southern Observatory (ESO) Fibre-fed Extended Range Echelle Spectrograph (FEROS) is a bench-mounted, thermally controlled, prism-cross-dispersed echelle spectrograph. It is designed to be a high-resolution (R=48000), high-efficiency (20 per cent), versatile spectrograph providing in a single spectrogram almost complete spectral coverage from 350 to 920nm.
