  • Optical pressure sealing coupling apparatus
    Patent number: 4798433
    Abstract: Apparatus for optically coupling and pressure sealing sections of an instrumentation probe, one of the sections being at a high pressure cryogenic environment and the other section being at ambient pressure. The apparatus includes a housing having a passageway within which elements are mounted for precisely locating a rigid optical fiber coupler and the probe sections so as to optically connect and maintain the ends of the probe sections together to permit signals to pass in both directions through the joint in two or more discrete channels. An adjustable positioning member acts to connect the external section of the probe to the housing in axial and rotation alignment with the interior section.
