Freja 430

Superior CO2 gas detection capability using T2SL technology. The highly uniform and stable 320x256 Freja array with 30 µm pixel pitch is combined with a dedicated CO2 filter to provide best-in-class optical gas imaging (OGI) detection capabilities.


The new Freja 430 detector takes advantage of IRnova’s T2SL technology breakthrough and wide optical aperture options (F/1.2 or F/2) to provide best-in-class gas detection capability for carbon dioxide having its absorption peak near 4.3 µm. The groundbreaking T2SL technology combines all the benefits of alternative detector materials (low NETD, excellent quantum efficiency, array uniformity and operability) without their drawbacks. Designing state-of-the-art optical gas detection and monitoring systems has never been so easy.


  • Optical gas imaging for any gas with absorption in 4.3 µm range
  • Optimized for carbon dioxide (CO2) detection
  • Handheld and battery powered cameras
  • Mobile and stationary platforms
