What inspection variables should be evaluated?
Normal coin relief and scratches can both form bright lines. Compare good samples under several lighting directions.
What lighting geometry fits this inspection task?
Oblique or low-angle lighting can darken a smooth background while allowing scattered light to reach the camera. Scratch visibility depends on direction, depth and illumination angle. Separate images from several directions may be needed.
Hold the part fixed and vary the light direction. Compare normal texture with actual defects rather than judging brightness alone. Check shadows, curved-surface highlights and motion blur. Repeat the test at production speed and across the permitted position variation before choosing a layout.

Before choosing a configuration?
For selection, specify the field of view, smallest target feature, height variation, cycle time and installation space. Use the specific product page and drawing to verify electrical ratings, dimensions and compatibility.
Separating coin relief from scratches?
Coin relief creates shadows and directional reflections that can resemble damage. Compare low-angle illumination from several directions with a more diffuse reference. Keep the same surface region in view during comparisons.
Rotate the coin and test both worn and unworn examples. Check characters, relief edges and flat regions separately. A useful arrangement should expose the target damage without treating normal design features as defects.
