ABSTRACT:
An optical system for an endoscope is disclosed as having a direction of view at an angle to its axis, and which transmits in full color contrast two-dimensional optical images from an object plane to a final image plane. The optical system comprises a first light relaying system, a fiber optic assembly and a second light relaying system. The first light relaying system includes objective lenses positioned to focus light rays from an object at the entrance of the fiber optic assembly. The first light relaying means also includes a prism for dispersing the light from the object and for providing a direction of view at an angle of 30 to 60 degrees with respect to the axis of the system. The second light relaying system comprises lenses which are focused upon the exit end of the fiber optical assembly and are arranged to form an image of light rays transmitted thereby at a final image plane. The second relay system also includes light dispersing means so disposed relative to the exit end of the assembly as to disperse the light rays received from each assembly to recombine them.
