What inspection variables should be evaluated?
Check for a dark area near the viewing aperture. Compare centre and edge behaviour using reflective samples.
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.

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.
Evaluating a flat diffuse source?
Check the usable illuminated field with the intended lens and workpiece distance. A flat diffuse assembly can simplify installation, but reflective samples may reveal the viewing opening or boundaries of the source.
Compare clean and defective samples at the centre and edges. Vary part height within its normal range. Select the arrangement that provides stable feature contrast rather than judging uniformity from a single polished sample.
