Thermal Reference Sources (TRSs) are hermetically sealed infrared calibration devices. They are most often used for real time calibration of infrared temperature sensors. Custom Thermoelectric's TRS devices contain a highly efficient radiating surface and feedback sensor (PRT). The emissive surface can be rapidly driven in both the cooling or heating direction (2 ºC/sec. typical). Incorporating a solid state thermoelectric module that has been ruggedized to withstand 25G in all directions. Wavelengths of 3 - 5 micron and 8 - 12 micron are typical. Standard and custom designs are available upon request.

Just some of the features available are;

  • Emitter sizes from 0.10 to 4.0 inches.
  • Proprietary high efficiency radiating surfaces with typical emmisivities of ≥.97
  • Outstanding point to point uniformity within emitter surface (0.5 ºC typical, up to 0.05 ºC)
  • Pixel to pixel uniformity's of ± 0.1 ºC
  • Blackbody temperature ranges of -65 to + 150 ºC
  • Slew rates of 2 ºC/sec. typical, faster rates available.
  • Patented ruggedization method to withstand high G requirements.
  • Window materials available with high transmittance and low reflectance coatings.
  • Un-sealed (open air) designs available.

  • If you think you have an unusual design requirement or cannot find what you want elsewhere, call us or email us.
