    Abstract: Radiant energy is transmitted to a probe element including an interior conical reflecting surface and a fluid sample chamber. Portions of the light which have been transmitted, partially attenuated, or scattered by a fluid sample in the sample chamber are directed by at least a portion of the interior conical reflecting surface to means for collecting the transmitted, partially attenuated, or scattered light. A stilling valve incorporated into the probe element enables elimination of entrained gas bubbles from the chamber. A specific application of the probe is disclosed in which a titration analyzer is combined with electro-optic signal conversion and processing circuits and a probe according to the invention to provide titration colorimetric endpoint determination in measuring the free fatty acid content of a fluid such as a edible oil or fat.

    Abstract: In a turbidimeter for measuring a turbidity of a test solution to be measured i.e. culture solution in a fermentation apparatus, a semiconductor laser diode and a semiconductor photodiode are integrally arranged in a detection portion of the turbidimeter in such a manner that a laser beam emitted from the semiconductor laser diode is made incident upon the semiconductor photodiode through the test solution. Moreover, a protection circuit for the semiconductor laser diode and the semiconductor photodiode is also arranged in the turbidimeter to cut off a current flowed therethrough when an environmental temperature becomes above a predetermined temperature. Therefore, the turbidimeter can be made small in size and light in weight, and the turbidity can be measured accurately over wide range.

    Abstract: Radiation-translating devices such as resonance backscatter cells and other fluorescent bodies receive incident radiation in a concentrated beam and emit processed radiation in diffuse form. The present system separates such processed radiation from any unprocessed incident radiation specularly reflected from the cell window by receiving both in an optical light pipe coaxial with the unwanted radiation. The light pipe is laterally immersed in an optical medium of such index that the unwanted radiation is retained by total reflection in the pipe and a major portion of the initially diffuse processed radiation is transmitted through the sidewalls to form an annular beam of moderate solid angle suitable for further processing by conventional optics. The same light pipe may also supply the beam of incident radiation to the translating device.
