Abstract

The optical design and performance of the visible/NIR imaging Fabry-Perot interferometers for the 3.6-m CFHT, the 2.2-m University of Hawaii Telescope, and the 3.9-m UKIRT (all at Mauna Kea) are described. The basic configuration combines a high-finesse etalon of free spectral range about 10 nm with a state-of-the-art CCD image-plane array. The criteria considered in selecting the CCDs and etalons are discussed; the quality of the data obtainable is illustrated with sample data (CFHT 658.3-nm emission line profiles of the central region of NGC 1068 and UKIRT B-gamma profiles of the Galactic center); and the instrument calibration and artefact problems are outlined. It is suggested that, while Fabry-Perot devices offer the best visible-NIR performance at present, Fourier-transform and long-slit spectroscopy show great promise for the future, especially in the IR.
