Abstract
A stereoscopic endoscope includes a proximal main body, an outer tube extended to a distal end of the endoscope and a pair of optical train subassemblies. Distal and proximal inserts in the distal and proximal ends of the outer tube, respectively, support the optical train subassemblies. First and second optical fiber bundles substantially fill all of the voids between the inner surface of the outer tube and the outer surfaces of the inserts and the optical train subassemblies.
