Abstract
An endoscope having an autoclavable replaceable sealed optical assembly without moveable parts. The sealed optical assembly is placed into an insertion tube of the endoscope. A focusing device is attached to the proximal end of the sealed optical assembly. The opposite end of the focusing device may be connected to an appropriate image-receiving device such as a CCD camera. The endoscope differs from conventional optical devices of this type in that its focusing is performed by shifting the image-receiving plane of the CCD camera with respect to an immobile plane of a image produced by optical elements of the sealed optical assembly.
