We describe an imaging Fabry-Perot instrument, and give examples of its astronomical applications. The salient features of the
instrument are: wide wavelength coverage (1 .5 to 2.4 m) with a single etalon, operation near the focal plane in a converging
beam, resolving power R'4OOO, relatively easy portability to other telescopes.
Keywords: Fabry-Perot etalon, near-infrared
The UNSW Infrared Fabry-Perot (UNSWIRF) is a narrow-band (R'4OOO) tunable filter for the near-infrared (1.5 to 2.4 pm),
designed to work with array cameras in an f/18 (or slower) beam, with a diameter of <70 mm. Currently, UNSWIRF is used in
conjunction with the IRIS camera at the f136focus of the Anglo-Australian Telescope (AAT). The etalon is a model ET7OWF
from Queensgate Instruments Ltd, with unique coatings that are able to operate all the way from 1 .5 to 2.4 pm. Potential
applications of the instrument range from the study of nearby star forming regions,1'2 planetary nebulae3 and supernova
remnants, to the nuclei and disks of nearby and active galaxies.4
