ABSTRACT:
A universal transparency adapter for use on flat bed image scanners. The transparency adapter, which is placed on the image window of an image scanner, utilizes circumferential back lighting to uniformly project through and illuminate the desired transparent image to be scanned. A circular or other perimeter surrounding light source provides lighting to the transparency original in an economical and simple manner. The inventive light source can also be integrated with a conventional scanner by using the inventive light source as a lid for the conventional scanner.
