LEDSSF Camera Testing Equipment

LEDSSF is a device to characterize a camera’s Spectral Sensitivity Function (SSF) or Quantum Efficiency (QE).  It also provides color correction metrics (CCM) for any combination of illuminant/materials.

  • 19 LED channels for sampling a camera’s spectral sensitivity curve.
  • High illumination uniformity (95%) at the center region (5 cm diameter)
  • CCM devised to cover multiple illuminants on a comprehensive selection of materials
    • Materials include coatings, textiles, printed materials, plastics, and skins
    • 4 types: 1) all CIE illuminants, 2) laboratory sources, 3) commercial sources, and 4) custom sources

*1:The number of LED kinds
*2:Actually 1000 steps can be used because some steps for low luminance calibration.
*3:When set light source without warm up time under enviroment temperature 25°, short-term stability is measureed during 24 hours and compared to average value.
*4:When set light source after 30 minutes warm up time under enviroment temperature 25°, long-term stability is measureed during 90 days and compared to average value.
