In the JDEM context, a Integral Field Spectrograph has been proposed to study Supernovae. The performances of this instrument are strongly connected with its detector characteristics. The large R&D effort in the SNAP collaboration combined with the performances improvement of Teledyne H2RG infrared detectors indicates that those devices are now able to reach the requirements of the JDEM/SNAP spectrograph.
