Paper Abstract

High performance large infrared detector arrays that meet the demanding requirements of the astronomy and civil space communities are available at Raytheon Vision Systems (RVS). This paper describes multiple detector materials in array formats larger than 1k × 1k developed by RVS for low-background applications. Raytheon features low noise readouts that have been demonstrated with a variety of detector materials: Si PIN, HgCdTe, InSb, and Si:As IBC. All of these detector materials have demonstrated excellent QE uniformity over wavelengths ranging from visible (optical) to 28 μm. RVS packaging capabilities address reliability, precision alignment and flatness requirements for both ground-based and space applications. Summary performance data of each of these materials on arrays with more than one million detector elements are presented. A look into the future will include "plug and play" mosaic packaging concepts; focal plane electronics; and increasing array formats to 4k × 4k and beyond.
