Features
- The thermopile sensor consists of a series of 44 thermoelements, forming a sensitive area of 0.5 x 0.5 mm2. The sensor is hermetically sealed into a TO18 metal housing, with optical filter. This standard filter allows measurements to be made in the spectral range above 5 µm wavelength. The thermosensor exhibits an almost white noise, comparable to an ohmic resistance. It has a constant signal versus frequency up to its frequency limit, and is directly proportional to incident radiation. The ther.
