A well-optimised spectrograph concept has been developed for the SNAP (SuperNova/Acceleration Probe) experiment. The goal is to ensure proper identification of Type Ia supernovae and to standardize the magnitude of each candidate by determining explosion parameters. The spectrograph is also a key element for the calibration of the science mission. An instrument based on an integral field method with the powerful concept of imager slicing has been designed and is presented. A prototype of the full concept is under development in France (CNRS/INSU/IN2P3), with a CNES and UC Berkeley support to provide the verification of the optical performances at the requirement level. A complete simulation of the instrument is also developed at pixel level and will be validated. This permits a detailed strategy for the future ground and in orbit calibration scenario.
