Abstract
A stereoscopic endoscope includes an outer tube with an internal cavity, an insert, first and second image forming assemblies, first and second optical fiber bundles, and a first adapter. The insert is positioned within the outer tube and has a first side and a second side each including a concave outer surface. The insert holds the first and second image forming assemblies in a parallel relationship. Each optical fiber bundle substantially fills a non-circular void in the outer tube defined as a cross- sectional area between a respective side of the insert and a respective portion of an inner surface of the outer tube. The first adapter is configured to connect at least one of the first optical fiber bundle and the second optical fiber bundle to an illumination source.
