Abstract

A coupler device for coupling an endoscope to a camera head includes a housing that defines an enclosed light path extending along an optical axis between first and second end portions of the housing together with mounting components for attaching the first end portion of the housing to an endoscope and the second end portion of the housing to a camera head so that the light path extends toward the camera head. A single lens mounted within the housing intermediate the first and second end portions magnifies an image from the endoscope in order to provide a magnified image to the camera head, the lens being a single refracting optical element for magnifying the image from the endoscope that is the sole refracting optical element for magnifying the image. A quick-release arrangement in one embodiment enables attachment of the endoscope by advancing the endoscope axially without a having to rotate it while a focusing ring enables fine focusing adjustments. An imaging system includes an imaging endoscope with a quick-release connector hub, a coupler device for attachment between the connector hub and a camera head, and an interchangeable eyepiece for interfacing the endoscope to a human eye.
