Indium Antimonide Detector Technology At Cincinnati Electronics Corporation

Cincinnati Electronics' Detector and Microcircuit Devices Laboratories have built and supplied Indium Antimonide detector devices for a wide range of applications for over 25 years. During that time, dramatic improvements have been made in many areas such as uniformity, area definition and noise performance at reduced temperatures. While still a binary compound, many processing modifications are possible to optimize various performance characteristics under different conditions. In addition, various amplifier configurations for both discrete and multiplexed modes can be utilized to best fit the requirements of varying background fluxes and varying focal plane temperatures. This paper describes the present status of InSb detector technology at Cincinnati Electronics, and how a wide variety of focal plane arrays, using cooling techniques ranging from liquid helium, liquid nitrogen, J-T cryostats, mechanical coolers and passive radiative coolers, are designed and built for applications ranging from low background infrared astronomy to high background ther al imaging.
