NOTES: 3. Optical measurements are made using small-angle incident radiation from a light-emitting diode (LED) optical source.
4. 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 ∆λ½ = 35 nm, and luminous efficacy = 75 lm/W.
5. 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 ∆λ½ = 47 nm, and luminous efficacy = 520 lm/W.
6. The 565 nm input irradiance is supplied by a GaP light-emitting diode with the following characteristics:
peak wavelength λ_p = 565 nm, spectral halfwidth ∆λ½ = 28 nm, and luminous efficacy = 595 lm/W.
7. The 635 nm input irradiance is supplied by a AlInGaP light-emitting diode with the following characteristics:
peak wavelength λ_p = 635 nm, spectral halfwidth ∆λ½ = 17 nm, and luminous efficacy = 150 lm/W.
8. Irradiance responsivity R_e is characterized over the range from zero to 5 kHz.
9. Saturation irradiance = (full-scale frequency)/(irradiance responsivity).
10. Illuminance responsivity Rv is calculated from the irradiance responsivity by using the LED luminous efficacy values stated in notes
4, 5, and 6 and using 1 lx = 1 lm/m².
11. 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.
