Abstract: An instrument that analyzes chemical properties of a specimen includes a probe that is used in place on the specimen for spectroscopic analysis. The probe has a probe body with a proximal end and a distal end, and a first optical fiber extends from the proximal to the distal ends. A temperature sensor is included in the probe body and is used so insure that the probe does not exceed a rated temperature limit or to monitor specimen temperature while, simultaneously, chemical composition information of the specimen is transmitted by the optical fiber. The probe can be inserted into a container holding the specimen and can yield both temperature and chemical composition information. The probe includes a plurality of metal coated fibers with the distal ends of the fibers positioned inside a bore in the probe. Braze material is placed on the probe near the bore and the braze material is then brazed to the metal coating on the ends of the fiber.

Abstract: A hollow-core photonic crystal fiber gas cell and method for preparing the same. The hollow-core photonic crystal fiber gas cell comprises a single-mode fiber, a fiber splicing protection sleeve, a hollow-core photonic crystal fiber, and a photoelectric detector. One end of the single-mode fiber is fusion spliced with one end of the hollow-core photonic crystal fiber to form a fusion splice and seal one end of the hollow-core photonic crystal fiber gas cell. The fiber splicing protection sleeve covers and protects the fusion splice. The other end of the hollow-core photonic crystal fiber is processed into an output end by fusion sealing, and the surface of the output end faces, but is not parallel to, a detection surface of the photoelectric detector.

Abstract: The method and apparatus as shown in the present invention is to measure the absorption of light by material contained in a liquid. A transmitted signal is sent through a measurement window to a measurement chamber to a target point just inside the measurement window. The reflected signal indicates the amount of light absorbed by a material in the measurement chamber which allows for the amount of materials in a liquid to be determined. Adjustments are made through an optical block and a light control molecule to correct for variations in light intensity.

A sensor body has a gap in which a sample of the oil may be received and a reflecting surface, the second end of the optical fibre being embedded in the sensor body and having an end face spaced from the reflecting surface across the gap. Light emitted from the optical fibre can pass through the sample of oil and be reflected by the reflecting surface back into the optical fibre. By interferometry of the respective signals, the condition of the oil can be determined.
