The eyepiece (6) is attached to the proximal end of a bundle of optical fibers in an outer sheath (7), which extends from the distal end of the endoscope. A locking device (21,22) with a spring (23) has balls (24) which grip the end of the bundle of fibers. The housing has first (10) and second (11) fastenings with a rotatable sleeve (9), holding first and second lens groups (1,2), which may be moved longitudinally. The lens groups may be moved together for focusing and toward or away from each other to alter the degree of magnification. |
