Abstract
Embodiments relate generally to gas detector systems and method, wherein a gas detector system may comprise at least one emitter configured to emit radiation in a beam path; at least one detector configured to receive at least a portion of the emitted radiation, wherein the emitted radiation generates at least two focused spots at the at least one detector; a ring reflector configured to direct the emitted radiation around the ring reflector toward the at least one detector, wherein the ring reflector comprises at least a portion of a spheroid shape, and wherein the ring reflector is configured to allow gas to flow through at least a portion of the beam path; and a processing circuit coupled to the one or more detectors configured to processes an output from the one or more detectors.
