Thermopile Power Sensors

Thermopile optical power 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. Our thermopile power sensors offer broadband, spectrally flat response, and calibrated plug and play operation with our optical power meters.
