An endoscopic video camera drape for completely segregating a video camera lens and camera assembly from an attached endoscopic lens assembly. The video camera is attached to a coupling. The coupling is shaped to hold a flared end of an endoscope. The drape has a conventional elongated flexible covering for covering the camera body and at least a portion of the cable of the camera. An optically transparent, flexible and tough polymeric film is attached in an airtight manner to the open end of the elongated flexible covering. The optically transparent bag is then placed over the coupling and is capable of receiving an endoscope and providing a transparent window between the video camera and endoscope without having to center a conventional rigid window. Preferably the polymeric film bag is made from coextruded, biaxially oriented polypropylene film.
