Abstract: An apparatus and method for conducting optical spectroscopy in a hostile environment comprises a light source, e.g., a laser or an incandescent light connected to a multiplexer for supplying high intensity light to at least two optical fibers. One of the optical fibers extends to a material in the hostile environment to be analyzed. The second optical fiber is connected between the multiplexer and a standard sample for yielding known spectroscopic results. Either the same or additional optical fibers are used to return light from the material to be analyzed. Each optical fiber has an end portion covered by a sheath to shield the optical fiber from the hostile environment. The sheath has an open end covered by a transparent window which is preferably made of diamond, again, to seal and protect the optical fiber in the sheath.

Abstract: A technique for gathering specific information from various remote locations, especially fluorimetric information characteristic of particular materials at the various locations is disclosed herein. This technique uses a single source of light disposed at still a different, central location and an overall optical network including an arrangement of optical fibers cooperating with the light source for directing individual light beams into the different information bearing locations. The incoming light beams result in corresponding displays of light, e.g., fluorescent light, containing the information to be obtained. The optical network cooperates with these light displays at the various locations for directing outgoing light beams containing the same information as their cooperating displays from these locations to the central location. Each of these outgoing beams is applied to a detection arrangement, e.g., a fluorescence spectroscope, for retrieving the information contained thereby.

Abstract: A clam-shell luminometer that, when closed, completely encloses an assay reaction mixture-containing reaction vessel and some portion of a reaction carousel or ring. The luminometer includes first and second portions that are coupled to each other, a photomultiplier tube, and plural fiber optic bundles that are optically coupled to the photomultiplier tube. First ends of the fiber optic bundles are disposed adjacent to the reaction vessel in the second portion so that the fiber optic bundles completely surround the perimeter or periphery of the reaction vessel.
