Thermal imaging systems: applications and calibration

Thermal Imaging Systems
Thermal Imaging Systems

NPL has extensive experience in the use and verification of active and passive thermal imaging systems for a wide range of practical applications such as medical diagnostics, low temperature quantitative spacecraft testing, in process monitoring (food, materials, etc.), defence applications (combustion) and calibration/validation systems. We can carry out real-time thermal measurements of processes and systems.

Our current capabilities include:

  • Research thermal imager
    • Wavelength of operation nominally 3 µm to 5 µm
    • Array 320 x 256
    • Speed of capture - nominally 150 Hz full frame, up to 20 kHz windowed images
    • High resolution, with addition lens providing up to 25 µm resolution
    • Temperature resolution 0.01 °C
    • Temperature range nominally - 40 °C to +1500 °C (extended range possible)

  • In field thermal imager
    • Wavelength of operation nominally 8 µm to 13 µm
    • Array 120 x 120
    • Speed of capture nominally 9 Hz
    • Temperature resolution 0.1 °C
    • Temperature range nominally - 40 °C to +1500 °C (extended range possible)

We can help with equipment specification, implementation of measurement good practice, validation of techniques and calibration of instruments.
