Abstract

A spectrally tunable solid state source based on Light Emitting Diodes (LEDs) is being developed at the National Institute of Standards and Technology (NIST). The tunable source will emulate the spectral distributions of various light sources and can be utilized in calibrations of spectroradiometers, photometers, and colorimeters with reduced measurement uncertainty. Design issues of the tunable source, LED characterizations, source-distribution realizations, and colorimetric applications are discussed.
