Abstract
A sterile drape serving to preserve the sterile integrity of an operating field is disclosed. The drape has a rigid optically clear window which allows a visible light beam, such as a laser beam, to exit a targeting device without refraction or distortion that could result in misalignment of the visible light beam relative to a targeted object. The rigid optically clear window is made of a material having an ability to transmit light and which ability remains substantially unchanged after the drape has undergone a gamma radiation sterilization process. The drape is positioned so that the optically clear window is located across the device window. The optically clear window is adjusted with respect to the device window so that a secondary light beam caused by distortion due to misalignment of the windows disappears and only the visible light beam travels toward the targeted object.
