We present the current design and status of the integral field spectrograph for the SNAP proposal for JDEM. The spectrograph is designed to provide needed spectroscopy for the SNAP Supernova Program ( Type Ia SN ID and spectrophotometry), for the SNAP Weak Lensing Program (photo-z calibration) and for the SNAP fundamental Calibration Program ( 1-2 % on calibrated stars).The design provides for a large field of view ( 10 arc sec) and moderate spectral resolution ( lambda/delta lambda >100) from .4 to 1.7 microns allowing spectroscopy of both stellar and extended sources. It is based on the use of an image slicer Integral Field Unit. A demonstrator unit has been built and tested and meets performance, control of scattered light and calibration accuracy. Funding for the spectrograph which is being developed in Marseille, France has been provided by CNES, CNRS (IN2P3 and INSU).
