The Fine Guidance Sensor instrument of the James Webb Space Telescope features a tunable filter imager (TFI) module covering the wavelength range from 1.5 to 5.0 \mum at a resolving power R=100 over a field of view of 2.2'x2.2'. TFI also features a set of 4 occulting spots for coronagraphy.

This paper presents the design of TFI and highlights two key TFI science programs: detection of first light, high-redshift Ly\alpha emitters and detection/characterization of exoplanets.
