Abstract
The present invention relates to a flame detector and protective cover with wide spectrum characteristics. The novel flame detector has wide spectrum sensitivity, which facilitates increased sensitivity to any sign of a flame or fire. The protective cover has wide spectrum transmittance characteristics. The protective cover facilitates reduced cleaning requirements and less disruption of the automated process for cleaning purposes. The wide spectrum transmittance characteristics of the protective cover enable it to be used with any flame detector utilizing non-ultraviolet sensing techniques.
