Abstract

Photovoltaic mercury cadmium telluride IR detector arrays having spectral response in the medium wavelength IR region out to 5 micrometers have been developed for thermal imaging applications. These detectors require cooling only to 180 K which can be provided by a thermoelectric cooler having six stages. The detectors have achieved noise-equivalent temperature difference performance less than 0.05 degree(s)C for an f/1.6 optical field of view. They are commercially available in a permanently sealed metal package with ceramic feedthroughs and a sapphire window.
