Two versions of a thermal detector have been developed combining broadband response over the entire near infrared-to-millimeter region, room temperature operation, solid state construction, and amenability to absolute calibration. The sensitive detector version has a noise equivalent power (NEP) near 7 x 10(-10) W/Hz((1/2)) with a time constant of 6 msec. The power measuring bolometer version has a sensitivity near 10(-8) W for a 3-sec time constant. The basic construction uses a flake thermistor as a temperature sensor in combination with an optimized radiation absorber.
已开发出两种热探测器版本，它们结合了在整个近红外到毫米波区域的宽带响应、室温操作、固态结构以及易于进行绝对校准的特性。灵敏探测器版本的噪声等效功率（NEP）接近7×10⁻¹⁰W/Hz½，时间常数为6毫秒。功率测量测辐射热计版本在3秒时间常数下的灵敏度接近10⁻⁸W。基本结构使用片状热敏电阻作为温度传感器，并与优化的辐射吸收器相结合。
