    Abstract: Method and apparatus for external cavity laser absorption spectroscopy There is disclosed an apparatus, and corresponding methods, for determining one or more characteristics of a sample in an absorption cell using laser absorption spectroscopy. For example, the characteristic may be concentration of a species in the sample. The apparatus comprises an external cavity semiconductor laser comprising a semiconductor gain medium within an optical resonator. The absorption cell is located within the optical resonator of the external cavity semiconductor laser so as to be optically coupled with the gain medium. A controller is arranged to provide a varied injection current to the semiconductor gain medium. A photodetector is arranged to detect laser light output by the external cavity semiconductor laser. An analyzer is arranged to determine one or more characteristics of the sample from behavior of the detected laser light output as a function of the varied injection current.

    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.

    Abstract: A portable, tabletop fluid sampling device simplifies spectral analysis to produce an accurate but inexpensive chromatic fingerprint for fluid samples. In one embodiment, the sampling device uses an array of variable wavelength LED emitters and photodiode detectors to measure Rayleigh scattering of electromagnetic energy from the fluid sample contained in a cuvette. Either the fluid itself, or particles suspended in the fluid can then be identified by performing spectral pattern matching to compare results of a spectral scan against a library of known spectra. A wide range of applications include substance identification, security screening, authentication, quality control, and medical diagnostics.
