What inspection variables should be evaluated?
Use separate samples for core edge chips and surface texture. Pay particular attention to curved faces and chamfers.
What lighting geometry fits this inspection task?
Coaxial illumination sends light close to the camera viewing axis. It can help separate flat reflective areas from markings, depressions and scratches. Tilt, curvature and protective films can change the result, so align the light, lens and sample together.
Start below saturation and adjust alignment while watching the target feature. Test good and defective parts from different batches. Check the field edges, material texture and lens reflections. An even background is useful, but does not by itself support defect contrast.

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.
Suppressing the background on magnetic cores?
Coaxial illumination can provide a useful bright-field reference on sufficiently flat surfaces. Compare it with directional light for chipped edges and scratches. The surface finish and local slope determine which defects become visible.
Test clean cores with normal texture alongside defective cores. Move the part within its expected position and tilt range. If the core is curved or strongly textured, evaluate separate views rather than assuming a flat-surface arrangement will remain uniform.
