ABSTRACT:
Method and apparatus for rapidly measuring any of a large number of characteristics of lamplight. Apparatus extracts from the illumination being measured seven narrow visible bands and one wider band of ultraviolet. The measured power in each of the visible bands is multiplied by a weighting coefficient and the combination of the products provides a number which is indicative of the lamplight characteristic being measured. The measured power in the ultraviolet band is separately weighted from the measurements in the visible bands.
