With thermopile CA2 radiant fluxes can be measured. It is sensitive to radiation from 0.2 to 50 µm, and has a total field of view of 20 º. The field of view is determined by cylindrical brass housing, that contains a conical reflector and a removable glass window.","The thermopile is very suitable for control (ovens) or demonstration (schools) purposes and can be used for reference-measurements.","The CA2 contains a thermopile detector that has a spectrally non-selective black coating. Therefore, the detector responds to the total power absorbed.","The thermopile output is a voltage that is proportional to the radiation that is received.","Irradiance measurements are easily affected by convection and thermal radiation losses to the environment. Therefore a glass window can shield the detector. By using this window, the spectral range is limited to 0.3 to 3 µm.","The thermopile is delivered with a calibration certificate.
