The Mid-Infrared Spectrometer and Imager (MIRSI) is a mid-infrared camera system built at Boston University for ground-based observing. MIRSI offers complete spectral coverage over the atmospheric windows at 8-14 and 18-26 μm for both imaging (discrete filters and a circular variable filter) and spectroscopy (in the 10 and 20 μm windows with resolutions of and 100, respectively). The optical design was optimized for use at NASA's Infrared Telescope Facility (IRTF). MIRSI utilizes a detector array with a plate scale of , covering a field-of-view of at the IRTF. MIRSI's optics provide diffraction-limited spatial resolution, and the instrument achieves 1 σ detection limits of 4 and 236 mJy at 10 and 21 μm, respectively, in 60 s of on-source integration time.
