Paper Abstract

A dedicated optimized spectrograph based on an integral field unit adopting an imager slicing concept has been developed for the SNAP (SuperNova/Acceleration Probe) experiment. A prototype for the SNAP application is undergoing test at Marseille (France) between LAM (INSU) and CPPM/IPNL(IN2P3) to provide the verification of the optical performances associated with the development of a complete simulation of the instrument. The goal of this demonstrator is to prove the optical and functional requirements of the SNAP spectrograph: diffraction losses, spectrophotometric calibration, image quality and straylight.
