Features
The thermopile sensor consists of a series of 116 thermoelements, forming a sensitive region
size of 545μm (diameter). 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
μ
m 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.
