Abstract
Light is generated in accordance with a desired spectral power distribution curve. A spectrum of light is generated with a plurality of different light sources. An optical measurement device measures the spectrum of light generated by the plurality of different light sources. The optical measurement device is able to detect light within the entire spectrum of light generated by the plurality of different light sources. The measured spectrum of light is used as feedback to vary the spectrum of light generated with the plurality of different light sources to approximate the desired spectral power distribution curve.
