Optical port apparatus and method of making the same

A method of providing an optical port, the method comprising:

• providing a housing having oppositely disposed first and second housing surfaces, a housing body extending therebetween, a housing aperture extending about a central axis of the housing body, a groove surrounding the housing aperture, the groove extending partially through the housing body and having a bottom groove surface longitudinally spaced from the second housing surface by a groove side wall, and a shelf located laterally between the groove and the housing aperture;
• placing a gasket in the groove adjacent the bottom groove surface such that the gasket surrounds the housing aperture;
• placing a window across the housing aperture;
• dispensing an elastomeric adhesive into the groove between the groove side wall and the window and the gasket, the adhesive substantially attaching the window to the housing;
• and
• fastening a bezel to the second housing surface adjacent the groove.

An optical port apparatus, the apparatus comprising:

• a housing having oppositely disposed first and second housing surfaces, a housing body extending therebetween, a housing aperture extending about a central axis of the housing body, the housing aperture being generally circular, a groove surrounding the housing aperture, the groove extending partially through the housing body and having a bottom groove surface spaced from the second housing surface by a groove side wall, and a shelf located between the groove and the housing aperture;
• a gasket located in the groove adjacent the bottom groove surface, the gasket surrounding the housing aperture;
• a window located across the housing aperture in contact with the shelf;
• an elastomeric adhesive located in the groove between the groove side wall and at least one of the window and the gasket;
• a bezel fastened to the second housing surface adjacent the groove;
• and
• a skin coat located both between the bezel and the window and between the bezel and the adhesive;
• wherein
• the window and the shelf are conductive and are adapted to conduct electromagnetic interference to the housing from the window through the conductive shelf and substantially prevent transmission of electromagnetic interference between the first and second housing surfaces.
