Thermopile Detectors

LASER COMPONENTS is pleased to represent Dexter Research Center who are a leader in the manufacture of stable, high quality, high output radiation sensing thermopile detectors with a linear dynamic range from the UV to long wave IR. Thermopile detectors are passive radiation sensing voltage-generating devices that require no bias or cooling and do not emit any radiation. 

Spectral sensitivity is defined by the selection of optical band-pass filters, with dozens of options available. Thermopile output is generally in the micro-Volt to milli-Volt range depending on target size, temperature, and radiance.

Thermopile detectors generate no 1/ƒ or microphonic noise, but only the Johnson noise of their resistance. Additionally, thermopile detectors provide a stable output for DC radiation up to a frequency limited by the time constant. Unlike pyroelectric detectors, no chopper or modulation is required.  Applications are broad and include the following:  

  • hand-held non-contact temperature measurements 
  • non-contact temperature measurements in industrial applications and process control 
  • infrared radiometry 
  • automotive exhaust gas analysis of CO, CO2, & HC 
  • medical gas analysis including anaesthetic, incubator CO and CO2, blood alcohol breathalysers 
  • fire detection 
  • blood glucose monitoring 
  • human presence and detection
  • custom sub-assemblies including mechanics and PCB’s
