Thermopile Sensor Physics - Newport

Thermopile Optical Power Sensors. Thermopile sensors are based on thermocouples. A thermocouple consists of two dissimilar metals connected in series. To detect radiation, one metal junction is typically blackened to absorb the radiation. The temperature rise of this junction with respect to another non-irradiated junction generates a voltage.

Thermopile Sensor Physics - Newport

The thermopile disc consists of a circular array of thermocouples. The optical radiation, e.g., laser beam, is absorbed by the disc generating the output voltage. The heat on the disc spreads radially across the thermopile on the reverse side of the disc where it is transferred to a heat sink that is convectively cooled by a fan or by water.
