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 diffraction grating and a prism with the appropriate characteristics are employed to provide a combined dispersive characteristic that is substantially linear over the visible spectrum. Radiation from the grating and prism is collimated by a lens towards a detector array. The grating or a telecentric stop between the grating and prism is placed at a focal point of the lens in a telecentric arrangement so that equal magnification is achieved at the detector array. If the detector array is replaced by a plurality of optical channels, a multiplexer/demultiplexer is obtained.

Abstract: The present invention provides a simple, robust, and versatile high-resolution spectrometer that is suitable for downhole use. The present invention provides a method and apparatus incorporating a spinning, oscillating or stepping optical interference filter to change the angle at which light passes through the filters after passing through a sample under analysis downhole. As each filter is tilted, the color or wavelength of light passed by the filter changes. Black plates are placed between the filters to isolate each filter's photodiode. The spectrometer of the present invention is suitable for use with a wire line formation tester, such as the Baker Atlas Reservation Characterization Instrument to provide supplemental analysis and monitoring of sample clean up. The present invention is also suitable for deployment in a monitoring while drilling environment. The present invention provides a high resolution spectometer which enables quantification of a crude oil's percentage of aromatics, olefins, and saturates to estimate a sample's gas oil ratio (GOR). Gases such as CO2 are also detectable. The percentage of oil-based mud filtrate contamination in a crude oil sample can be estimated with the present invention by using a suitable training set and chemometrics, a neural network, or other type of correlation method.

Abstract: Concentric spectrometers are plagued with internal reflections due to inherent nature of more than one optical surface possessing a common center of curvature. Reflections from optical surfaces arise when there is a difference or change in the refractive index of the media in which an optical beam or ray of a given wavelength is propagating. Internal reflections in concentric optical systems can produce a myriad of undesirable optical phenomenon at the image plane such as multiple images of an object, interference fringes, and stray light. As a result a loss in contrast or detection limit arise from such phenomenon in which light or detectable radiation that impinges on the image plane does not add to the formation of the intended image, (stray light). The present invention produces high quality images without the optical phenomenon(s) that arise from internal reflections by removing the reflected radiation from propagating through the optical system.
