Paper Abstract

FALCON (a Fiber spectrograph with Adaptive optics on Large fields to correct at Optical and Near-infrared) is an original concept for a next generation instrumentation at ESO VLT or at future ELTs. It is a multi-objects integral field spectrograph with multiple integral field small units, each being coupled with atmospheric tomography in order to reach spatial and spectral resolution ideally suited for distant galaxy studies: typically 0.15 - 0.25 arcsec and R>=5000 in the 0.8-1.8 μm wavelength range. In the FALCON concept the adaptive optics correction is only applied on small and discrete areas selected on a large field. This approach implies to develop some miniaturized devices for adaptive optics correction and wavefront sensing. We present here some recent technological results.
