Microscopic cracks or flaws in surface of a workpiece are often detected with fluorescent dye. Dye is spread over surface to be inspected and then washed off. When piece is viewed under ultraviolet light, a glow is seen from dye trapped in any flaws. Intensity of fluorescence gives a rough indication of depth of defect. Fluorescent inspection procedure is fast, inexpensive and simple to perform.
