Abstract

A spectrally adjustable radiance source based on light emitting diodes (LEDs) has been constructed for spectral responsivity measurements of radiance and luminance meters. A 300-mm integrating sphere source with adjustable output port is illuminated using 30 thermally stabilized narrow-band LEDs covering the visible wavelength range of 380–780 nm. The functionality of the measurement setup is demonstrated by measuring the relative spectral responsivities of a luminance meter and a photometer head with cosine-corrected input optics.
