THz Detectors

Our sensors are pyroelectric-based and can thus be used very easily, and at room temperature. You can choose either a standalone head with on-board electronics or go with our T-Rad meter and a separate sensor. We also have small discrete terahertz detectors in TO5/TO8 packages.



  • Relative Measurements from 0.1 to 30 THz Broadband, room temperature operation, easier to use and less expensive than a Golay cell
  • Flat Spectral Response Get the best precision accross the entire wavelength range
  • Measure Higher Powers Up to 3 W of continuous power with the THZ12D model, the highest in our THz range of products
  • Use with a Universal Monitor No need for an exclusive monitor. This unique THz detector works with our standard universal monitors:
  • Large Aperture Models range from 9 to 12 mm Ø aperture
  • Calibrated at 10.6 µm THZ-D detectors are calibrated at a single wavelength (10.6 µm) and include wavelength correction data from 10.6 to 440 µm. They are used for relative measurements outside that range
