Machine Vision Inspection Application Cases

POMEAS optical applications team · Reviewed by Tiger Xie · Published 2026-10-16

Application cases describe what was inspected, which optics and illumination were used, and what changed in the process. They are the fastest way to find an analogous problem: if the part, tolerance and surface resemble yours, the optical arrangement is a credible starting point.

Cases are grouped by industry below. Read them as engineering precedent, not as a guarantee, because every deployment depends on the part tolerance, the mechanical envelope and the lighting environment at the station.

2. How to use this index

Start from the industry group closest to your part. Within a group the entries are ordered by how much of the surrounding problem they resolve; integration and changeover cases generally carry more of the system than single-measurement cases. Cross-read the selection index for the underlying rules.

3. Frequently asked questions

Can I reuse an application case directly for my own inspection?

Use it as an optical precedent, not as a specification. A case tells you which lens class, magnification and illumination made a similar part measurable, and what the measured outcome was. Your own tolerance, mechanical envelope and surface finish still have to be checked with a trial on real parts before the arrangement is fixed.

Why are so many cases about fiber optic end faces?

Because that inspection combines several hard constraints at once: features measured in micrometres, a transparent or polished surface, and a requirement to read geometry and defects in one pass. Arrangements that work there transfer well to other small precision parts, and the lighting lessons apply broadly.

What should I look for first when reading a case?

Object-side pixel size and the illumination geometry. Those two numbers largely determine whether the arrangement can work for your part. Magnification, working distance and camera model follow from them, and often more than one combination reaches the same result.

How do multi-product lines avoid stopping for changeover?

Usually with a motorised zoom lens plus a stored magnification position per product, so the changeover is a command rather than a manual adjustment. The cases below on changeover and integration describe how the position is stored and repeated, and what repeatability the process needs from the lens.

Are the images in these cases from production or from trials?

Each case states its own provenance in the article text, and the imaging conditions that were recorded are listed there. Where a condition such as camera model or illumination level was not recorded, the article says so rather than filling the gap with an assumption. Treat any figure that is not labelled as measured as an estimate.

How do I move from a case to a quotable configuration?

Reduce the case to the parameters it proves: object-side pixel size, field of view, working distance, depth of field and illumination. Send those to an engineer with your part drawings and tolerance, and the configuration can be matched to published product data rather than to the case narrative.
