Dexter Thermopiles for Infrared detection
Dexter Research Centre is a leader in the manufacture of high quality; high output
Bismuth Antimony thin film and Silicon based infrared sensing thermopiles.
Thermopiles have a very wide spectral response from the UV to the far infra red and
the wavelength of response can be limited by the addition of various filters or windows
which can be either be built into the detector encapsulation or can be external.
Thermopile detectors are voltage-generating devices, which can be thought of as
miniature arrays of thermocouple junctions. Our detectors are hermetically sealed
in TO-18, to-5 or TO-8 transistor type packages, purged with inert gas and heat
treated to ensure long term stability. Since the detector acts as pure resistance,
it generates no 1/f or microphonic noise, but only the Johnson noise of its own resistance.
Applications for thermopiles are limitless, but include:
Non contact temperature measurement
Gas analysis
Hazard control including flame and explosion detection
Horizon sensors
