What are the capabilities of TFI?
The Tunable Filter Imager (TFI) uses a Fabry-Perot etalon to provide narrow-band near-IR imaging over a field of view of 2.2 by 2.2 arcmin2 with a spectral resolution of R ~ 100. The wavelength coverage is 1.6 to 4.9 micron with a gap between 2.6 and 3.1 micron. The TFI detector is a single 2048 by 2048 pixel detector array with 65 milliarcsec pixels. TFI features four coronagraphic occulting spots and a non-redundant mask for high-contrast imaging applications. TFI imaging will reach 126 nJy (AB=26.1) point source sensitivity at 3.5 microns, 10 sigma in 10,000 seconds. • What are the capabilities of MIRI? The Mid-Infrared Instrument (MIRI) provides imaging and spectroscopy over the wavelength range 5 to 28.5 micron. The imaging module provides broad-band imaging, coronagraphy and low-resolution slit spectroscopy. It has a 1024 by 1024 pixel detector array with 110 milliarcsec pixels. The coronagraphy is done with quarter-phase coronagraphs at 10.65, 11.4 and 15.5 microns, and a Lyot s
