Abstract
A new generation of near infrared (NIR) detectors have been developed by Teledyne for the SNAP/JDEM (SuperNova/Acceleration Probe) project. The new detectors are hybridized HgCdTe on a multiplexer with indium bump bonded. Since 2004, Teledyne and the SNAP collaboration have tried to characterize and improve the large format ( 2 k × 2 k ) H2RG detectors to meet the SNAP requirements. The results for quantum efficiency and total noise as an integration of a H2RG in a spectrograph demonstrator are presented.
