FLITECAM: current status and results from observatory verification flights
Abstract
This paper describes the current status of FLITECAM, the near-infrared (1 - 5 μm) camera and spectrometer for NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA). Due to a change in schedule FLITECAM's delivery was advanced, allowing it to be co-mounted with the HIPO instrument and used on four flights in October 2011 for observatory verification. Although not part of FLITECAM's commissioning time, some preliminary performance characteristics were determined. Image size as a function of wavelength was measured prior to the installation of active mass dampers on the telescope. Preliminary grism spectroscopy was also obtained. In addition, FLITECAM was used to measure the emissivity of the telescope and warm optics in the co-mounted configuration. New narrow band filters were added to the instrument, including a Paschen alpha filter for line emission. Results are illustrated.
