ABSTRACT:
An adapter for coupling an endoscope to a camera head. The adapter includes a zoom ring, barrel, focusing ring and chassis. A lens, slidably mounted within the barrel, moves axially within the barrel in response to rotation of the zoom ring thereby varying the transmitted size of the image of the proximal end of the endoscope. Rotation of the focusing ring produces axial movement of the barrel within the chassis for focusing the image at the camera head.
