The only requirement is that the radiation be absorbed in order to heat the detector. This effect is improved by the application of a black layer, and the spectral sensitivity is flat from the UV to the far IR range (exception: ST series). However, application is most widespread in the infrared spectral range. The thermopile is a DC detector.
