FLITECAM is an infrared camera operating in the 1.0 - 5.5 μm waveband. It consists of a 1024x1024 InSb detector with 0.475''x0.475'' pixels and uses refractive optics to provide an 8' diameter field of view. The instrument has a set of filters for imaging, and grisms for moderate resolution spectroscopy. The filter suite consists of standard Barr filters used for imaging at J, H, K, L and M in one filter wheel. A second filter wheel holds a selection of narrow-band imaging filters including Pa-α, Pa-α continuum, 3.07 μm H2O ice, 3.3 μm PAH, L-narrow and M-narrow. Additionally there are order sorting filters for use with the grisms. A selection of three grisms is available to provide medium resolution (R ≈ 1500) spectra over the entire wavelength range.

FLITECAM can be co-mounted with the High Speed Imaging Photometer for Occultations (HIPO) providing simultaneous optical and near-infrared imaging.

Scientific/Technical Abstract

FLITECAM is designed to test the SOFIA telescope assembly imaging and infrared background quality. FLITECAM will provide seeing-limited imaging from 1 - 3 µm and diffraction-limited imaging from 3 - 5.5 µm to cover science applications motivated by good atmospheric transmission and low thermal background. FLITECAM will also provide moderate resolution spectroscopy from 1 to 5.5 µm. FLITECAM will operate simultaneously with the Special Class Instrument HIPO (High-speed Imaging Photometer for Occultations) on SOFIA.
