A science instrument known as the Tunable Filter Imager (TFI), is packaged with the guide camera (FGS), but is functionally independent. The TFI will be used solely for science observations and will have a selectable band of resolution R~100 across its 2.2' x 2.2' field between 1.5 - 5 µm.
The Canadian Space Agency will provide the TFI to the JWST Project. The prime contractor is Com Dev. The Principal Investigator for the TFI is René Doyon from the Université de Montréal.

The FGS and TFI underwent an alignment and risk mitigation campaign in a cryogenic environment at the David Florida Laboratory (DFL) in Kanata, Ontario (Canada) in Dec 2010 and Jan 2011. Preparations are currently underway for the final test activities in the summer and fall of 2011.
