ABSTRACT:
A surgical drape construction wherein a tubular body, peripherally assembled to a local lens aperture in a drape, is adapted for removable concentric engagement to the exposed end of the objective-lens barrel of a microscope, wherein the tubular body mounts a flat optically transparent element which closes the body, and wherein the flat transparent element is fixedly so inclined that a geometric normal to the flat transparent element is at an acute angle to the axis of concentric engagement. Would-be reflections are thereby deflected off-axis, and microscope viewing is materially enhanced for all subject-matter aspects with respect to incident light.
