Abstract
In one aspect of the disclosure, a gas sensor is provided, comprising: a chamber for containing a gas sample in use, and a radiation source adapted to emit radiation within a first waveband. A photoluminescent material, upon absorption of radiation of a first wavelength within the first waveband, emits radiation of a second wavelength, the photoluminescent material being responsive to the presence of a target gas species in the gas sample. The gas sensor further comprises a luminescence detector assembly. The luminescence detector assembly is adapted to detect radiation of the second wavelength and output a corresponding measurement signal related to the concentration of the target gas species. An optics assembly is adapted to receive radiation emitted by the radiation source and to converge the radiation towards a location at which the luminescence detector assembly cannot receive radiation.
