A fiberoptic endoscope includes an axially movable optical fiber guide to compensate for focusing effects, such as thermal expansion or mechanical tolerances. The distal end portion of the optical fiber guide is secured to the distal end of the endoscope while the proximal end portion is permitted to move axially relative to a proximal housing portion of the endoscope. The proximal housing portion includes an eye lens unit secured thereto. A decoupling lens unit is fixed to the proximal end portion of the optical fiber guide so as to move therewith with respect to the eye lens unit.
