Abstract
The use of optical fibres in astronomical instrumentation has been going on at the Anglo-Australian Observatory (AAO) for the past four years. The major application of fibres has been for multi object spectroscopy, and a system known as FOCAP (Fibre Optic Coupled Aperture Plate) has been in regular use on the 3.9m Anglo-Australian Telescope (AAT) as a general user instrument for the past three years. FOCAP has undergone a program of continual development with improvements and new facilities to cope with the steadily increasing and diversifing demand. This paper seeks to describe the current status of the present FOCAP system and detail the experience we have gained from regular fibre observing. A brief survey of suitable astronomical fibres currently avaliable will be given as well as an outline of some future developments with fibres at the AAO.© (1986) COPYRIGHT SPIE--The International Society for Optical Engineering.
