ABSTRACT:
A method for focusing an objective lens of endoscope comprising dividing said objective lens into a front lens group and a rear lens group, arranging an optical fiber bundle so as to have its end surface on the rear side of said rear lens group and focusing said objective lens by displacing said rear lens group together with said optical fiber bundle. This method makes it possible to afford high magnification level for the objective lens even when it is brought into focus with an object located at a short distance.
