Performance

One of the four science instruments aboard the James Webb Space Telescope (JWST) is the Tunable Filter Imager (TFI) provided as part of the Canadian contribution of the JWST Fine Guidance Sensor. The TFI features a low-order Fabry-Perot etalon which enables imaging spectroscopy at an average resolving power of 100. TFI also includes a coronagraph for high-contrast imaging applications such as exoplanet imaging. In this paper we demonstrate experimentally a TFI prototype etalon's performance of speckle suppression through multi-wavelength imaging, a technique widely used by existent and future ground-based high contrast imaging instruments. The improvement in contrast ranges from a factor of ~10 at large working angles increasing to a factor of ~60 in the inner regions with very high signal. This result is consistent with our theoretical model.
