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.
