H. K. Corning this subject is the result of improved detection techniques, particularly the use of detectors at liquid helium temperatures. Unfortunately, the terrestrial atmosphere greatly restricts Infrared astronomers by allowing them to detect radiation only in narrow transmission win dows and by presenting

H. K. Corningsuch as indium antimonide or mercury cadmium telluride (MCT), whose bandgaps match the photon energy of the radiation to be detected. The MCT alloy system is the most versatile such system and can be used in detectors with cut-off wavelengths varying between at least 20 µm and 2 µm. The special purp
