Abstract
A flame detector including: a plurality of detectors; a plurality of filters; a plurality of non-imaging optical concentrators having an entrance arranged to receive light incident on the flame detector and an exit arranged to deliver the light to a coupled detector. A first of the plurality of filters transmits light of a first wavelength range to a first of the detectors, and a second of the plurality of filters transmits light of a second wavelength range to a second of the detectors, wherein the second wavelength range is different from the first wavelength range.
