ABSTRACT:
A method of providing a clear image on a component including the steps of providing a transparent member having first and second opposite sides, providing a layer of opaque material on the second side of the transparent member and ablating away a predetermined pattern of the opaque layer by directing a laser beam at portions of the first side of the transparent member corresponding to the predetermined pattern, the laser beam passing through the transparent member to contact and ablate the opaque layer and provide a clear image through the transparent member corresponding to the predetermined pattern.
