Abstract: Dual band filters and detectors are described herein. A detector can include a filter for filtering light from a scene to be imaged, the filter having at least one window that only allows light to pass there through that is within a medium wavelength infrared wavelength range and at least one window that allows light to pass there through that is not within a medium wavelength infrared wavelength range and an imager array that receives the filtered light that passes through the filter.

Abstract: A flame detector includes an infrared detector and a first window covering the infrared detector. A second window is positioned in front of the first window. The flame detector is adapted to reject light having a wavelength below approximately 2 ?m and to reject light having a wavelength above approximately 6 ?m, allowing detection of flame from multiple sources. In variations, the windows in combination with the infrared detector may provide the rejection or a band pass filter provides the rejection. Still further variations utilize notch filters or a band reject filter to provide notches of light to the infrared detector corresponding to the wavelength of different flame sources to be detected.
