CdTe photodetectors capable of operating continuously at 750F were packaged for flight testing as an aircraft engine fire detector. The sensors at temperature could detect a photosignal of 50 microwatts per square centimeter with a signal-to-noise ratio of over 201 and an output impedance of 1000 ohms. The units consist of two CdTe sensors separately sealed in hermetic TO-8 headers which are mounted inside a larger hermetically sealed housing made of inconel. The detectors meet MIL-Spec 810B including temperature cycling up to 750F, well above the capability of all the available semiconductor infrared detectors. Author
