The JWST Tunable Filter Imager (TFI) is a sensitive camera that shares the optical bench of the Fine Guidance Sensor (FGS). It provides JWST with the capability of imaging a 2.20 × 2.20 field-of-view through narrow-band filters over a wavelength range of 1.5 - 5.0 μm, with a non-functional region between 2.5 and 3.2 μm. The narrow-band filters are characterized by spectroscopic resolving powers of 75 to 120 for central wavelengths selected by the user. The TFI is also capable of high-contrast imaging with a choice of four coronagraphs and an aperture mask. Here, we provide a brief summary of the technical specifications and scientific capabilities of the TFI and present an overview of the upcoming ground calibration and on-orbit commissioning activities.
