The Ohio State University Imaging Fabry-Perot Spectrometer (IFPS) is designed for two-dimensional imaging spectrophotometric and kinematic studies in the wavelength range of 3400-10000A. Presently it uses four etalons providing low and medium spectral resolutions (lambda/delta-lambda) of 1200 in the 4500-7500A wavelength range, and lambda/delta-lambda=4500 in three bands covering the 3400-4000A, 4100-5500A, and 6000-7000A wavelength regions. These resolutions make it applicable to a wide range of galactic and extragalactic imaging spectrophotometry problems. The IFPS has also found use as direct imaging focal camera (without the etalons). The instrument development and basic design philosophies are described, and some scientific results from the Fabry-Perot mode of hte instrument are presented.
