    Abstract: The invention concerns spectrophotometer devices that provide for ultrasensitive measurements through a reflection interaction with matter. Embodiments of the invention use sealed housings (112, 600, 700) lacking an internal light source, and reflection based sample and reference cells. In some embodiments a substantially solid thermally conductive housing (600, 700) is used. Oilier features of preferred embodiments include particular reflection based sample and reference cells. A total internal reflection embodiment includes a prism (302, 322, 622a, 623a) including an interaction surface, a detector, a lens that focuses a beam output from the prism onto the detector, and a closed interaction volume having an inlet and an outlet for delivering gas or liquid to the interaction surface. In a specular reflection embodiment, a reflective surface (402, 422) is used. In a diffuse reflection embodiment a matte surface (502, 522) is used and the matte surface produces scattering.

    Abstract: A method and apparatus is provided for determining a property of an analyte using a sensing layer whose optical response changes with the analyte. The apparatus includes a housing (12) with an optically transparent window (13) for receiving the sensing layer (36). The window passes optical stimulation (41) to the sensing layer and the optical response (43, 45) from the sensing layer. A stimulating light emitter (40) is coupled to a first face of an optical body (38) monolithically coupled to the window and a light detector (42, 44) is coupled to a second face of the optical body for receiving the response. The optical response changes as the concentration of the analyte changes. Reference molecules (62) included in the sensing layer can provide a calibration signal to a second light detector mounted on a third face of the optical body. The first, second and third faces of the optical body are different and not coplanar.

    Abstract: A non-dispersive infrared (NDIR) multi-gas analyzer (405) has an optical element (950) that is positioned with respect to the axis of incident IR radiation such that it passes nearly all of the IR energy within a narrow band pass to one detector (540) and reflects nearly all of the IR energy outside the narrow band pass to another detector (535). Thus, the optical element (950) simultaneously functions both as a narrow band pass filter and a beam splitter, which transmits nearly all the IR radiation within a band pass and reflects nearly all the IR radiation outside the band pass. Additionally, the separation of the incoming energy can be achieved without an extended roll off. This allows using a reference transmission band that is very close to the absorption band of the gases of interest. It more specifically allows using a reference transmission band that is located between the absorption bands for hydrocarbons and carbon dioxide in an infrared analyzer that uses beam splitters.

    Abstract: This invention is a multiple reflection type cell 102 that makes it possible to reduce a dead space resulting from a position adjusting mechanism and to adjust the light to a desired optical path length without complicating a structure. The multiple reflection type cell 102 comprises a cell body 2 where a cell chamber 2S is formed, two or more reflecting members 31,32,33 that are mounted on the cell body 2 and whose reflecting surfaces 3x locate in the cell chamber 2S and a position adjusting mechanism 4 that adjusts a position of the reflecting member 32, 33 relative to the cell body 2. The cell body 2 has a mounting part 221that communicates the cell chamber 2S and the outside and on which the reflecting members 32,33 are mounted. A seal member 7 that seals a gap between the cell chamber 2S and the outside of the cell body 2 is arranged between the reflecting member 32, 33 mounted on the mounting part 221 and the cell body 2 so that the gap between the cell chamber 2S and the outsider of the cell body 2 is sealed by the seal member 7. The position adjusting mechanism 4 is arranged outside of the cell chamber 2S.
