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

λp = 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

λp = 524 nm, spectral halfwidth Δλ½ = 47 nm, and luminous efficacy = 520 lm/W.

8. The 640 nm input irradiance is supplied by a Al

InGaP light-emitting diode with the following characteristics:

peak wavelength

λp = 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 Re 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 fO from a straight line between zero and full scale, expressed as a percent of full scale.
