発明の名称 (英語) GAS DETECTION DEVICE, GAS DETECTION METHOD, AND OPTICAL COMPONENT
発明の概要(英語) This gas detection device (10) is provided with: a cell internal space (130) supplied with a target gas that exhibits an absorption peak in the absorption spectrum; a light source (410) capable of producing light of at least a wavelength belonging to the absorption peak; and a photodetector unit (420) capable of detecting light emitted from the light source (410) and propagated through the cell internal space (130). The gas detection device (10) is further provided with an electrically conductive thin film (220) in which a plurality of optical apertures (222) are arranged in regular fashion such that the transmission peak of the transmission spectrum overlaps the absorption peak of the absorption spectrum on the wavelength axis. The electrically conductive thin film (220) is situated on the optical path leading from the light source (410) to the photodetector unit (420), and in such a way that contact with the target gas within the cell internal space (130) is possible.
