Abstract: A hermetically sealed fiber optic connector or feed through, the connector for connecting at least two fiber optic cables and including a center member having two extensions, with each of the extensions being cylindrical and coaxial. Each of the extensions includes a first engagement means and a first sealing means, with the center member defining a channel axially disposed relative to the extensions. A first connector includes a backshell, with the backshell including a second engagement means in complementary relationship with the first engagement means of a first one of the extensions, and a second sealing means in complimentary relationship with the first sealing means of the first one of the extensions. The first connector includes a ferrule seat and a ferrule joined to the ferrule seat, and includes a cylindrical crimp socket joined to the ferrule seat. The crimp socket defines an axial channel for receiving a first fiber optic cable.

Abstract: An endoscope contains no adhesives, epoxies, or other organic materials. The endoscope includes a set of lenses held in position by cylindrical spacers. A pair of windows seal the ends of the endoscope, and prevent the lenses and spacers from falling out. The windows are brazed to the endoscope. Due to the use of brazing, no adhesives are needed to hold the lenses or windows in place. Thus, one can sterilize the endoscope in the high temperature environment of an autoclave, without risking damage to the optical components. The brazing produces a hermetic seal which enables the endoscope to function properly in an environment of high temperature or high pressure, or in chemically abusive environments.

Abstract: The feedthrough device includes first and second half housing members, each of which has an internal chamber. The feedthrough device further includes a removable header member that fits within the chambers of the first and second half housing members when they are threaded together. The first half housing member has a threaded protrusion which fits into a threaded aperture located in the wall of a sealed structure, such as the wall of a vacuum furnace. The threaded protrusion arrangement includes a first "O" ring which seals the periphery of the aperture in the wall of the sealed structure. The header has first connectable terminals on one end and second connectable terminals on the other end. In between the first and second connectable terminals of the header there is located a plate member which fits along the edge of the first half housing member chamber; and located between that edge and the plate is a second "O" ring.
