| Abstract: | Uncertainties associated with measurements of LEDs are extremely important.By choosing specific quantities,devices under test and equipments, the process of uncertainty budgets by example can be analyzed.Spectroradiometer measurements are traceable to NIM spectral irradiance scale.The particular LED was chosen because it also has an independent NIM traceable calibration via another path and can provide verification of measurements.The uncertainty of spectral radiant intensity measurements of LEDs is analyzed through experiment and calculation. |
