What inspection variables should be evaluated?
Label coating texture, lettering and damage separately. A smoother background must not hide subtle capacitor-surface changes.
What lighting geometry fits this inspection task?
Diffuse lighting spreads illumination over a broad area to reduce concentrated reflections. It is useful to evaluate curved parts, glossy packaging and uneven textures. Dome, flat and square diffuse lights have different openings and working distances.
Check background brightness at the centre and edges and look for reflections of the camera opening. Diffusion may also reduce fine-scratch contrast; a separate directional exposure can help. Evaluate colour, markings and defects on real samples instead of selecting a light only for a visually pleasing image.

Light from different directions reveals surface details.
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 capacitor texture and damage?
Capacitor coatings and printed markings can produce normal texture that competes with cracks, dents or contamination. Begin with diffuse illumination, then compare directional light for features that depend on surface slope.
Use samples from the expected colour and finish range. Rotate the component and inspect its edges as well as its face. Confirm that the final contrast distinguishes known defects from acceptable printing and moulding variation.
