During 1983, the advisory committee for instrumentation at the Anglo Australian Telescope (AAT) recommended that, as a matter of high priority, an échelle spectrograph should be procured for the f/36 coudé focus. The aim was to satisfy the high spectral-resolution needs of the community which, hereto, have been neglected. We at University College London (UCL) were invited to consider the design and our proposal was subsequently accepted by the Board. We are now at an advanced stage in optimizing the optical system, and mechanical design is proceeding. We plan to test the complete system in the laboratory at UCL prior to installation and commissioning at the AAT which we anticipate will be during 1987.
This paper is intended as a general introduction to the design philosophy of the instrument, paying particular attention to the properties of the detectors with which it will be used. Some implications on the requirements for similar instruments at future very large telescopes are also discussed.
