Freja 330

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


The Freja 330 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 VOC gases (volatile organic compounds) having an absorption spectrum around 3.3 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 systems has never been so easy.


  • Optical gas imaging for any gas with absorption in the 3.3 µm range
  • Optimized for detection of methane, ethane, propane and other VOC gases
  • Handheld and battery powered cameras
  • Mobile and stationary platforms
