Here you will find general information and documents about the instrument BTFI (Brazilian Tunable Filter Imager) designed and built to be used at SOAR Telescope. Most of BTFI’s development happened at IAG/Poli at the University of São Paulo, in collaboration with INPE and LNA, LAM (France) and LAE (Montreal, Canada).
