Abstract

The James Webb Space Telescope (JWST), the successor to the Hubble Space Telescope, will draw on recent improvements in infrared array technologies to achieve its goals and mission. In order to best meet the goals of JWST, NASA is funding a competition between two near infrared detector technologies: InSb detector arrays from Raytheon Vision Systems and HgCdTe detector arrays from Rockwell Scientific. The University of Rochester, in collaboration with Raytheon, is testing near infrared InSb detectors in a 2048 x 2048 array format to meet the stringent requirements for JWST. Results from characterization under top level requirements, such as noise, quantum efficiency, well capacity, pixel operability, etc., are discussed. Dark current and its contribution to the total noise are analyzed.
