CL-70F
The Konica Minolta CL-70F is an illuminance spectrophotometer that adds flicker measurement capability to comprehensive spectral analysis of light sources. The CL-70F measures illuminance, chromaticity, CCT, CRI, spectral distribution, and flicker index/percent for complete lighting quality assessment. It is particularly valuable for evaluating LED and PWM-controlled lighting systems where flicker can cause visual discomfort and health effects.

Measurement Principle of the CL-70F
The CL-70F combines a high-speed photosensor for flicker waveform capture with a diffraction grating spectrometer for spectral analysis. The flicker measurement captures the temporal variation of light intensity and calculates flicker index and flicker percentage per IEEE 1789 guidelines.
Applications of the CL-70F
LED lighting flicker assessment, display quality evaluation, workplace lighting compliance, and photobiological safety testing.
Q: What flicker metrics does the CL-70F measure?
A: The CL-70F measures flicker index, flicker percentage, and flicker frequency.
