NOTES: 5. Optical measurements are made using small-angle incident radiation from a light-emitting diode (LED) optical source.
6. The 470 nm input irradiance is supplied by an InGaN light-emitting diode with the following characteristics:
peak wavelength λ_p = 470 nm, spectral halfwidth Δλ½ = 35 nm, and luminous efficacy = 75 lm/W.
7. The 524 nm input irradiance is supplied by an InGaN light-emitting diode with the following characteristics:
peak wavelength λ_p = 524 nm, spectral halfwidth Δλ½ = 47 nm, and luminous efficacy = 520 lm/W.
8. The 640 nm input irradiance is supplied by a AlInGaP light-emitting diode with the following characteristics:
peak wavelength λ_p = 640 nm, spectral halfwidth Δλ½ = 17 nm, and luminous efficacy = 155 lm/W.
9. Output frequency Blue, Green, Red percentage represents the ratio of the respective color to the Clear channel absolute value.
10. Irradiance responsivity R_e is characterized over the range from zero to 5 kHz.
11. Saturation irradiance = (full-scale frequency)/(irradiance responsivity) for the Clear reference channel.
12. Nonlinearity is defined as the deviation of f_O from a straight line between zero and full scale, expressed as a percent of full scale.
