    摘要: The present invention is thus directed to an automated system and method of varying the optical path length in a sample that a light from a spectrophotometer must travel through. Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Such a methodology and system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.

    摘要: A photometer is provided with modular lighting units wherein each lighting unit includes one or more light emitters. A user may select a desired lighting unit and install it within a photometer base unit, and thereafter activate one or more of the emitters (which may emit light of different wavelengths) to illuminate a specimen. The light provided by the specimen in response can then be captured at a detector, and analyzed to provide an indication of the specimen's characteristics. Different lighting units may optionally include one or more input light adapters (filters or polarizers which modify the light provided by the emitter(s) to the specimen), and/or one or more output light adapters (filters or polarizers which modify the light provided by the specimen to the detector). Users may therefore select lighting units with emitters and light adapters which are particularly suited for detection/analysis of particular specimens and/or components therein.

    摘要: An optical device is provided that includes a converging lens device, a transmitting optical fiber, a sample holder, and a receiving optical fiber. The converging lens device focuses light onto the transmitting optical fiber, which receives the focused light through an entrance face and transmits the light from an exit face, through a sample, and onto the receiving optical fiber. The sample holder holds the sample for analysis. The receiving optical fiber receives the light through an entrance face of the receiving optical fiber after transmission through the sample. The converging lens device is positioned to focus the light onto the entrance face of the transmitting optical fiber such that a half-angle of the angular distribution of the focused light that reaches the entrance face of the transmitting optical fiber is selected to underfill an entrance aperture of the entrance face of the receiving optical fiber in both a spatial dimension and an angular dimension.

    摘要: An apparatus is described in which an optical fiber is mounted within a fiber optic holder which includes the non-rotating shaft of a linear actuator. The fiber holder may be held captive in order to restrain the fiber holder and, consequently, the fiber mounted therein, from rotating during operation of the linear actuator, thereby resulting in linear travel with minimal rotational effects and minimal change in optical alignment of the fiber during travel. In addition, an optical path length sensor in conjunction with an optimized absorbance method of operation is utilized herein to provide micron precision of the displacement between respective receiving and transmission fibers so as to enable precise absorbance measurements from about 0.005 up to about 2.0 Absorbance Units for any given path length.
