Dark-field Lights

​Dark-field lights highlight surface structure using low-angle lighting (typically in a ring format) to graze light onto the surface of an object. The low angle light is then only reflected into the camera from angled surfaces leaving any flay areas dark.

The classical demo for this technique is that of a coin showing all of the raised surfaces highlighted against a dark background. This type of light is ideal for showing up scratches on flat objects , to detect gaps in seals or gaskets or show a raised feature or embossed text clearly on a part. Due to its nature the light should be applied as close to the surface of the object as is practical
