A method of making a plurality of adjacent light pipe elements, the light pipe elements adapted for use in illuminating a microfiche. The ends of the light pipe elements are spaced apart from each other, to thereby coincide with spaced microimages on a microfiche. The method includes the steps of die-deforming a plastic sheet in the general form of a flat elbow, placing saw-tooth cuts at one end thereof, and subsequently rolling the sheet about an axis.
