Abstract: An endoscope coupler includes a sealed chamber and a lens assembly longitudinally movable within the chamber for focusing an image to be received by a video camera. Spaced permanent drive magnets located exteriorly of the chamber are magnetically coupled with respective permanent driven magnets secured to the lens assembly in the chamber for moving the lens assembly simultaneously with movement of the drive magnets. A focusing ring is rotatable but not longitudinally movable about the chamber and translates the drive magnets and, therefore, the driven magnets and lens assembly longitudinally in response to focusing ring rotation. Frictional retaining rings disposed between the chamber and the focusing ring resist movement of the focusing ring to provide enhanced tactile response when the focusing ring is manually moved by an operator.
