Infrared Systems and Photoelectronic Technology IV. Edited by Dereniak, Eustace L.; Hartke, John P.; Levan, Paul D.; Longshore, Randolph E.; Sood, Ashok K. Proceedings of the SPIE, Volume 7419, pp. 741907-741907-10 (2009)

The James Webb Space Telescope, an infrared-optimized space telescope being developed by NASA for launch in 2014, will utilize cutting-edge detector technology in its investigation of fundamental questions in astrophysics. JWST's near infrared spectrograph, NIRSpec utilizes two 2048 × 2048 HdCdTe arrays with Sidecar ASIC readout electronics developed by Teledyne to provide spectral coverage from 0.6 microns to 5 microns. We present recent test and calibration results for the "pathfinder NIRSpec detector subsystem" as well as data processing routines for noise reduction and cosmic ray rejection.
