Abstract: The invention concerns measurements in which light interacts with matter giving rise to changes in light intensity, and preferred embodiment spectrophotometer devices of the invention provide for ultrasensitive measurements through a reflection interaction with matter. The level of light source noise in these measurements can be reduced in accordance with the invention. Preferred embodiments of the invention use sealed housings lacking an internal light source, and reflection based sample and reference cells. In some embodiments a substantially solid thermally conductive housing is used. Other features of preferred embodiments include particular reflection based sample and reference cells. A total internal reflection embodiment includes, for example, a prism 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 is used instead of a prism. In a diffuse reflection embodiment a matte surface is used instead of a prism and the matte surface produces scattering. Aspects of the invention include identification of noise-contributing components in spectrophotometry and the select set of preferred features in a given embodiment, and noise levels very near the shot noise limit may be realized with application of preferred embodiment devices.

Abstract: A multifunctional sensor system for an intrinsic type optical sensing fiber. A numerical aperture controlling optical input element for the excitation fiber may maximize the amount of sensing fiber modulated return light. The excitation fiber may be centered in a ring or linear array of return fibers, to inject excitation light into the return light poor center of the sensing fiber; and to capture return light from the return light rich outer parts of the sensing fiber. Tipping the return fibers with respect to the sensing fiber may increase their capture of high numerical aperture return light. The sizes and number of the adjacent ends of the excitation, return and sensing fibers may be selected to minimize the effects of any lateral displacement between the adjacent ends. The sensing fiber may generate both reference and sensor return light; and a ratiometric output signal may be derived from the reference and sensor return light which may be free of certain system errors. Ribbon-like sensor and sensing fibers may be provided; along with a transition fiber if the sensor and sensing fibers are of different sizes. An annular, possibly tapered, waveguide may be provided around the sensing fiber, to better capture the return light. The waveguide may either pass the target objective; or it may be hollow, and define a sample chamber for the target objective. The ends of the sensing fiber and/or the annular waveguide may be mirrored, to dramatically increase the output of return light, and thus, the sensitivity of the sensor system.

Abstract: A molecular characterization detector includes a scattering cell containing a sample for molecular characterization, a light source for directing a light beam through the cell so that the light beam is scattered by the sample, optical elements for selecting from the scattered light a measurement beam comprising light that is scattered by the sample from a predetermined portion of the cell in a predetermined range of angles relative to the optical axis, and a detector for detecting the measurement beam and providing an output electrical signal representative of the measurement beam. The detector typically selects light scattered from a central portion of the scattering cell at angles in the range of 14.degree. to 16.degree.. A single spherical lens is preferably utilized. As a result, interference from stray scattered light is minimized. A beam dump attenuates the light beam after it passes through the scattering cell. Additional detectors detect light scattered at 90.degree. to the light beam. The outputs of the detectors are processed to provide molecular characterization of the sample.
