Abstract

The Fine Guidance Sensor (FGS) of the James Webb Space Telescope (JWST) features a tunable filter imager (TFI) module covering the wavelength range from 1.5 to 5.0 μm at a resolving power of ~100 over a field of view of 2.2'×2.2'. TFI also features a set of occulting spots and a non-redundant mask for high-contrast imaging. This paper presents the current status of the TFI development. The instrument is currently under its final integration and test phase.
