What inspection variables should be evaluated?
Bar length and incidence angle jointly determine coverage. Recheck ends and part-height differences after angle changes.
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.
Balancing coverage and grazing angle?
Position a bar so that its useful footprint covers the inspection region at the intended angle. Check both ends of the field. Lower angles can reveal shallow texture while also increasing shadows and sensitivity to height.
Rotate known scratches relative to the bar and test expected height variation. Compare a second direction if necessary. Record mounting references and exposure so the contrast remains reproducible.
