Typical absorption of Thermopile Detector Coating.
The Choices |
We offer three different thermopile detectors differing in the window material. We coat the active detector element with a black, absorbing coating. The typical spectral properties of this coating are modified by the transmission properties of the windows used with them, which we list in Table 1. |

Calibration |
The calibrated detectors are shipped with a single value responsivity, representative of the response throughout the spectral range of the detector. |
