Abstract
To take advantage of the large luminosity-resolution product of the Fabry-Perot interferometer used in tandem with modest aperture telescopes, a Fabry-Perot interferometer has been developed that is widely adaptable to a variety of extended source observations. The instrument is designed for adaptability across a range of optical and near infrared spectral lines from 550 nm to 1,100 nm, which are characterized by a wide range of velocity distributions of the emitting species. The system features twin etalon configuration to provide extended free spectral range and to enhance contrast when observations include bright reflected solar or twilight backgrounds. Although the optical path and all optical elements of the system are readily accessible, the instrument is ruggedized for transportability and extended remote field operation once optically configured. State-of-the-art, but proven detectors (GaAs photomultipliers, large charge coupled devices, and Ge-Nitride integrating detectors) are featured to optimize instrument sensitivity, and are modularly adaptable.
