The thermopile sensor consists of a series of 44 thermoelements, forming a sensitive area of 0.5*0.5 mm2.
The sensor is hermetically sealed into a TO-5 metal housing, with an 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.
