Machine vision applications requiring precise detection and measurement of edges and small defects often demand challenging illumination set-ups. To maximize the contrast between an important detail and the background of an image, consider using an illumination technique called silhouetting illumination. When used in conjunction with a high quality telecentric imaging lens, a silhouetting lighting set-up will reduce scattering effects that may occur in other illumination systems, allow for more accurate edge detection, and provide better overall image contrast.
