“…The multiplexer design used cryo-CMOS ͑complementary metal oxide semiconductor͒ technology. 27 The arrays for channels 1, 2, and 3 are antireflection coated with SiO; the channel 4 array is coated with ZnS. The arrays are read out using four output amplifiers.…”

The National Aeronautics and Space Administration's Spitzer Space Telescope (formerly the Space Infrared Telescope Facility) is the fourth and final facility in the Great Observatories Program, joining Hubble Space Telescope (1990), the Compton Gamma-Ray Observatory (1991-2000), and the Chandra X-Ray Observatory (1999). Spitzer, with a sensitivity that is almost three orders of magnitude greater than that of any previous ground-based and space-based infrared observatory, is expected to revolutionize our understanding of the creation of the universe, the formation and evolution of primitive galaxies, the origin of stars and planets, and the chemical evolution of the universe. This review presents a brief overview of the scientific objectives and history of infrared astronomy. We discuss Spitzer's expected role in infrared astronomy for the new millennium. We describe pertinent details of the design, construction, launch, in-orbit checkout, and operations of the observatory and summarize some science highlights from the first two and a half years of Spitzer operations. More information about Spitzer can be found at http://spitzer.caltech.edu/.

“…1 The University of Rochester has achieved low noise, low dark current and high quantum efficiency, with good system electronics and optimized clocks and biases, using Raytheon produced high quality near infrared InSb array detectors which are ideal for space borne telescope missions, such as SIRTF. 2,3,4,5,6,7,8 We have chosen to work with Raytheon because InSb, on a suitably designed multiplexer, can meet or exceed all of the NGST requirements operating at a temperature of 30K. A detailed list of requirements and goals for NGST are provided by M c Creight et al 9 The most relevant requirements and goals, as they pertain to this paper, include:…”

The astronomical community has benefited from the scientific advances in photo-detection over the last few decades, from optical CCDs to infrared array detectors, for both large ground-based telescopes and space-borne telescopes. NGST, the successor to the Hubble Space Telescope, will draw on the improvements in infrared array technologies to achieve its goals and mission. The University of Rochester, in collaboration with Raytheon and NASA Ames Research Center, is developing and testing near infrared InSb array detectors to meet the stringent requirements for NGST. The latest development involves a suitable multiplexer in a 2048×2048 format that will be bump-bonded to an InSb array. Twenty of these arrays will be required for NGST imaging and spectroscopy. We present results for pathfinder 1024 × 1024 arrays. This is a companion work to the paper in these SPIE proceedings by

“…Both array types are 256×256 pixels in size, and have the same physical pixel size of 30 µm. Cryo-CMOS technology was used in the readout multiplexer design (Wu et al 1997). The arrays were anti-reflection coated with SiO for Channels 1, 2, and 3, and with ZnS for Channel 4.…”

The Infrared Array Camera (IRAC) is one of three focal plane instruments in the Spitzer Space Telescope. IRAC is a four-channel camera that obtains simultaneous broad-band images at 3.6, 4.5, 5.8, and 8.0 µm. Two nearly adjacent 5.2×5.2 arcmin fields of view in the focal plane are viewed by the four channels in pairs (3.6 and 5.8 µm; 4.5 and 8 µm). All four detector arrays in the camera are 256×256 pixels in size, with the two shorter wavelength channels using InSb and the two longer wavelength channels using Si:As IBC detectors. IRAC is a powerful survey instrument because of its high sensitivity, large field of view, and four-color imaging. This paper summarizes the in-flight scientific, technical, and operational performance of IRAC.
