▓ Features

The thermopile sensor consists of a series of 116 thermoelements, forming a sensitive

region size of 545 µm (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 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 thermopile sensors are

featured with an additional temperature reference resistor on the same chip. The standard

version of temperature reference resistor is housing connected to ground.
