The Coudé Spectrograph was an instrument attached to the coudé focus of the ESO 1.52-metre telescope (coudé is the French word for elbow). Three cameras equipped with photographic plates as detectors were available. It has two cameras working at f/6 and f/14. Dispersions from 1A/mm to 18a/mm are available with a selection of three gratings, each with ruled areas of 20 x 30 cm. The Coudé Spectrograph was installed at the coudé focus of the ESO 1.52-metre telescope at the La Silla Observatory in May 1969. It was decommissioned from the ESO 1.52-metre telescope in mid 1980s.
