Abstract: A hermetic seal between an optical element and a metal mount or housing using a fluoropolymer. The fluoropolymer is dispersed along the interior edge of the metal mount. The metal mount and fluoropolymer are then heated to a temperature exceeding the melting point of the fluoropolymer. Once heated the optical element is pressed into the metal mount and allowed to cool. The metal mount, optical element and thickness of fluoropolymer are sized to provide an interference fit between the metal mount and optical element.

Abstract: An endoscope coupler with a split focus ring having direct engagement between the focus ring and the lens cell. The endoscope coupler may also have a changeable lens cartridge which can be replaced when moisture penetrates and ruins a the previous lens cartridge. Additional features may include branding security key which prevents use of replacement parts from third parties.
