A fog-free endoscope comprises an elongated tube (10, 12) defining an optical path (18) extending from a distal end (20) of the endoscope. A front window (22) is fixed to the endoscope distal end (20), and heating means (24) is disposed in the endoscope proximate the window (22) to provide heat to the window to maintain the window (22) in a fog-free condition.

Une fenêtre frontale (22) est fixée à l'extrémité éloignée (20) de l'endoscope, et un dispositif de chauffage (24) est placé sur l'endoscope, à proximité de la fenêtre (22), afin de chauffer celle-ci et d'éviter ainsi toute formation de buée.
