Abstract
An adapter for coupling an endoscope to a camera head. A front window assembly includes a cup-like element for insertion within the chassis of the adapter. A plurality of resistive heating elements is mounted to an annular printed circuit board that is fitted within the cup-like element. The resistive elements are energized by the camera power source to heat the adjacent front window of the adapter. Radial heating of the window raises the moisture-pressure gradient of its surface above that of adjacent metal surfaces, eliminating condensation from the surface of the window.
