ABSTRACT:
An endoscope optical system comprising rod lenses between the objective and ocular lenses has the feature that gradient rod lenses, whose lengths each end centrally between two intermediate images, are installed with small spacings between the ocular and objective lenses. To this end, the rod lenses terminate centrally between two intermediate images and the distal and proximal gradient rod lenses have no more than half the length of the spacing between said intermediate images.
