Paper Abstract

A visible and infrared spectrograph based on integral field method (IFU) using the slicer technology is proposed for the SNAP(SuperNovae/Acceleration Probe) mission. The spectrograph is a key element to control supernovae Type Ia measurements and to calibrate standards stars at the per cent level. The current concept has a low spectral resolution (about 100) and is under-sampled in the infrared arm. A demonstrator has been manufactured and is used to validate the performances. The calibration procedure has been developed using a full simulation of the instrument at the pixel level and tested with the demonstrator. We present the first experimental results performed in the visible range and we compare them with the results predicted by the simulation.
