Test cameras from the near infrared to thermal

Imaging systems designed to capture infrared light vary greatly depending on application, from the automotive and security industries to remote sensing and facial recognition. Imatest offers targets for the near, mid and long wave infrared that can be analyzed with Imatest Master and Imatest IT.

Near Infrared

  • 720 to 1100 nm, on reflective and transmissive substrates
  • NIR variants of our standard inkjet charts: ISO eSFR, Checkerboard, SFRplus, SFRreg and custom designs
  • Tonal adjustments compensate for the change in contrast at longer wavelengths
  • Tailored to specific spectral responses and filters, such as systems centered at 850 or 940 nm
  • Photographic prints, such as the Photographic ISO eSFR, keep similar contrast in the NIR

Mid Wave Infrared

  • 3 to 5 µm
  • An emissive SFRplus target for longer wavelength testing
  • Heating elements and thermally sensitive paints create thermal contrast
  • Slanted-edge MTF measurements in the mid wave infrared

Long Wave Infrared

  • 8 to 15 µm
  • Black body emitters for testing the resolution of thermal imaging systems
  • A uniformly heated back plate, with an adjustable heating differential to the thermally isolated front plate
  • Single slanted edge, SFRplus and custom patterns
  • 120 V standard; a 240 V version on request, or a voltage transformer for 220 to 240 V outlets
