LWIR uncooled thermography cameras

What are LWIR uncooled bolometer cameras?

Uncooled LongWave InfraRed (LWIR) thermography cameras are used to detect and quantify the thermal radiation of an object within their field of view. Most of the R&D, industrial, security and defense markets require thermal infrared cameras to be maintenance free goods, avoiding costs on cooler refilling and joint replacement. This is why the dedicated uncooled microbolometer technology was developed. When calibrating a LWIR imaging camera such that the camera can indicate the temperature of the object, we have converted the imaging camera into an LWIR uncooled thermography camera.

What are LWIR uncooled bolometer cameras used for?

LWIR uncooled microbolometer thermography cameras are used for all types thermography applications where a thermal sensitivity of 50mK to 100mK and a radiometric accuracy of +- 1˚C to 2˚C is required.

Typical R&D applications:

  • Temperature distribution on plane and rocket engines
  • Metallurgy processes
  • Life science
  • Lock-in thermography
  • Diagnostics on chemical reactions

Typical industrial applications:

  • Slag detection in the steel industry
  • Sorting applications
  • Temperature homogeneity on products heated in kilns and furnaces (e.g. steel & glass industries), …
  • Monitoring moulding processes
  • Inspection of train axels and car breaks
  • Solar cell inspection / production
  • PCB testing, validation and verification
  • Soldering and welding
  • IR Automation in Automobile Industry

Typical Safety applications:

  • Indoor or outdoor fire detection e.g. in waste bunkers or storage sites
  • Critical vessel monitoring like torpedo cars within the steel industry
  • ...

What do we offer?

Xenics offers various solutions for uncooled thermography applications depending on the operating environment of the system. The Gobi camera family is perfectly suited for R&D and primarily clean industrial environments as it comes in an IP45 enclosure. For more harsh and dusty environments our Serval series offers best radiometric performance in a ruggedized, IP67 certified, housing. . In both camera families we offer high and low imaging resolution, such that an optimized choice can be made for cost versus performance.

These cameras are very flexible in use. You can optimize the integration time on the detector so that imaging speed – especially in sub-windowing mode – as well as temperature range and detector sensitivity are tuned in the best possible way to meet your requirements.

We offer our Gobi camera family with a wide variety of interchangeable lenses so that the thermal camera is easily adaptable to the thermal scene. The Serval series comes with a fixed lens and extra dust cover. Other options like water cooling, air purge, solar protection cover, etc … are also available on this ruggedized thermal camera.

Thermal calibration

Our longwave infrared thermography cameras are thermally calibrated to guarantee a correct measurement. We offer 4 standard calibration ranges:

  • -20˚C and 120˚C
  • 50˚C and 400˚C
  • 300˚C and 1200˚C
  • 1000˚C and 2.000˚C


What features are needed?

  • Temperature Measurement Accuracy +/- ≤ 2%
    Describes the accuracy of the thermal measurement. The lower the deviation, the higher the accuracy of your measurement.
  • High thermal sensitivity
    Thermal cameras need to have a high sensitivity level (low NETD) to detect the smallest temperature differences
  • High frame rate
    The higher the frame rate, the faster you can do your thermal measurements.
  • Easy connectivity
    We offer several different interfaces for an easy integration into your system
  • Protection grade
    We offer cameras with an IP rating up to IP67 for thermal imaging in harsh environments
