A thermopile is an electronic device that converts thermal energy into electrical energy. [1] It is composed of several thermocouples connected usually in series or, less commonly, in parallel . Such a device works on the principle of the thermoelectric effect , i.e., generating a voltage when its dissimilar metals (thermocouples) are exposed ...
Thermopile laser sensors find their use mainly where sensitivity to a wide spectral range is needed or where high laser powers need to be measured. Thermopile sensors are integrated into laser systems and laser sources and are used for sporadic as well as continuous monitoring of laser power, e.g. in feedback control loops.
An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually called radiometers , photometers , laser power meters (can be photodiode sensors or thermopile laser ...
Power meters are also less helpful for off-road disciplines like cyclocross and mountain biking. They can be great training tools, but if you ride on muddy, wet trails often and need to spray your ...

The magnitude of the voltage depends on the types of wire being used. Generally, the voltage is in the microvolt range and care must be taken to obtain a usable measurement. Although very little current flows, power can be generated by a single thermocouple junction. Power generation using multiple thermocouples, as in a thermopile, is common.
A thermopile sensor which is sensitive to radiation in a broad range from 200 nm to 100 μm; A silicon dome or window with a solar blind filter coating. It has a transmittance between 4.5 μm and 50 μm that eliminates solar shortwave radiation. A temperature sensor to measure the body temperature of the instrument.
