What inspection variables should be evaluated?
Check the central aperture and part curvature under diffuse ring light. Save exposure conditions for each separately activated zone.
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.
Testing diffuse ring illumination?
Align the ring opening with the camera view and set the working distance using the actual part. Diffuse illumination can soften hotspots, but the resulting image still depends on curvature, source size and viewing geometry.
Compare the complete surface and edges with known defects. Check changes caused by rotation and height. If smoothing the background also suppresses an important defect, evaluate an additional directional exposure.
