Abstract

The invention provides an endoscopic visualization system utilizing a selectively reflective element that allows wide-angle and/or retrograde viewing and forward viewing with an endoscope having a single imaging camera or other imaging means. The endoscopic visualization system can be switchable from a forward-viewing mode to a wide-angle or retrograde viewing mode or to a mode that allows simultaneous viewing of forward and wide-angle and/or retrograde images.
