ABSTRACT:
A non dispersive optical gas analyzer is disclosed which uses thermopiles as optical detectors. The thermopiles are formed of an array of interconnected thin films of dissimilar metals deposited on a heat conductive substrate to form a multitude of thermocouples. The array is configured in such a manner that a number of the thermocouples are employed to compensate each thermopile output signal for changes in ambient temperature.
