Abstract: A gas sensor comprises a cavity for containing a gas, means for generating radiation which is transmitted through the cavity and includes one or more wavelengths which is absorbed in use by a gas to be detected; and a detector for detecting radiation which has passed through the cavity. The walls of the cavity are sufficiently reflective to the radiation that the cavity is substantially uniformally illuminated with the radiation.

Abstract: A laser spectrometer can be operated for analysis of one or more analytes present in a combustible gas mixture. The spectrometer can include one or more features that enable intrinsically safe operation. In other words, electrical, electronic, thermal, and/or optical energy sources can be limited within an hazardous are of the spectrometer where it is possible for an explosive gas mixture to exist. Methods, systems, articles and the like are described.

Abstract: An optical gas sensing apparatus includes an explosion-rated device electronics enclosure. An explosion-rated sensing enclosure has a light transmitting element to allow light to pass out of and into the sensing enclosure. The sensing enclosure is operably coupled to the explosion-rated device electronics enclosure by a feed-through. In one aspect, an internal volume of the sensing enclosure is less than or equal to about one fiftieth of the volume of the explosion-rated device electronics enclosure. In another aspect, the thickness of the light transmitting element is less than or equal to about 3 millimeters. A light source is disposed within the sensing enclosure and is operably coupled to the device electronics. A detector is disposed within the sensing enclosure and is also operably coupled to the device electronics.
