Profile: Teledyne Judson Technologies is a manufacturer of infrared detectors. Our brands include InAs™, InSb™ and Geranium™. Our products include germanium detectors, indium gallium arsenide detectors, indium arsenide detectors, lead sulfide detectors, lead selenide detectors, indium antimonide detectors, PC mercury cadmium telluride detectors, preamplifiers, position sensors, dewars, connectors, flanges and temperature controllers. Our CM21 assembly is designed to provide heatsinking and temperature control for cooled photoconductive and photovoltaic detector product line. It is designed to simplify integrating a cooled detector into an existing system with a customer supplied amplifier. Our TC8 is a self-contained temperature controller for use with the thermoelectric coolers. It operates in conjunction with a thermistor, located in the detector assembly, to precisely measure and regulate the temperature of the cooler detector.
