Thermopiles for Solar, Temperature and Power Measurement video.

Dexter Research thermopiles are selectable over a wide spectral range, fast responding, and DC capable.

All objects above absolute zero radiate electromagnetic energy. Our thermopile traps this energy and produces a voltage output proportional to the incident power without having to touch the object it is measuring. Power measurement thus becomes as simple as selecting a suitable optical or IR window to limit the incoming radiation to your area of interest, whether that be solar, temperature, or some other spectral power.
