Paper Abstract

The evolution, current status, and planned improvements of the FLAIR fiber-optic-link multiobject spectroscopy system used on the 1.2-m UK Schmidt Telescope of the Anglo-Australian Observatory are reviewed and illustrated with diagrams and sample spectra. Consideration is given to the original FLAIR system using photographic film to record spectra, the introduction of a slow-scan cryogenic CCD camera in 1986, the problems of focal-surface coverage and sensitivity in the prototype FLAIR, the improved Panache fiber feed and on-chip pixel binning scheme installed in 1988, and the dispersion options offered by the FLAIR-Panache system. The limitations of the present FLAIR configuration are discussed, along with improvements involving (1) the use of a new spectrograph with Schmidt optics for both collimator and camera and (2) advanced plate-holder and positioner systems making it possible to load FLAIR into the telescope in a few seconds instead of an hour.
