The Smart Tunable Filter is a new spectrograph providing a continuous field of view of 4'×4' sampled at 56 mas using the technology of imaging Bragg Tunable Filter (BTF) and a scanning Fabry-Perot tunable filter. 48 holographic gratings photoinscripted helicoidally in a doped glass cylinder and preceded by 4 tunable BTF are used to study 52 emission lines selected between the main OH night sky lines. The Smart Tunable Filter offers the advantage to be an "opto-ecological" system providing a complete separation between spectral and spatial information avoiding problems from image slicing and slit effects. The design can fully operate at cryogenic temperatures for IR purpose. The Fabry-Perot mode operates at a spectral resolution of 5000 and can be removed to provide a 100 spectral resolution over the 48 fixed gratings. Main results obtained in laboratory from the first prototype developed in collaboration with Photon etc. Inc. are presented. Merit factors to compare this instrument to similar ones are studied versus sciences cases.
