Abstract
An infrared emitter is described. The infrared emitter comprises an infrared source, a housing, and infrared optics. The infrared source emits electromagnetic radiation with a peak intensity at a radiation wavelength within the range of 2 to 15 microns. The housing has an aperture, and is arranged to house the infrared source. The infrared optics is arranged to direct the electromagnetic radiation emitted from the infrared source through the aperture to outside the housing.
