Abstract
A hand held radiation detector may be used for scanning of a surface from a distance to obtain a gross indication of temperature variations in the surface. The radiation detector is provided with a nosepiece having a conical cup therein which can be placed directly against a surface. The radiation sensor views the surface through the cup to obtain an accurate indication of temperature substantially independent of the emissivity of the surface. The radiation sensor and a temperature sensor are potted with high conductivity material in an insulating sleeve within the nosepiece. The nosepiece is of high conductivity material and is thermally connected to a main housing which serves as a heat sink. Temperature indications are obtained from the sensed radiation indication by means of a piecewise linear gain analog circuit.
