Research findings
Filter-difference study
Against the 79-record Machine Vision Optical Sorting Keyword Candidate Study, this 78-record cohort shares 71 records. Only 7 occur here and 8 only in the reference; the union contains 86. These are filter-membership differences, not company entries or exits.
| Company cohort | Directly linked pages | Share of public archive | Archive date |

An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.
Filter differences and comparison link
The largest recorded sub-industry participation gap is for Instrumentation and testing equipment: 20/78 here versus 19/79 in the reference, an absolute difference of 1.6 percentage points. The cohorts have overlapping company IDs and are not independent samples.
| sub-industry | Focal count/base | Reference count/base | Participation gap (pp) |
|---|---|---|---|
| Instrumentation and testing equipment | 20/78 | 19/79 | +1.6 |
| Transport equipment and application systems | 2/78 | 1/79 | +1.3 |
| Industrial software and information services | 2/78 | 1/79 | +1.3 |
| 3D automated optical inspection equipment for PCBs | 1/78 | 0/79 | +1.3 |
| Semiconductor manufacturing equipment | 1/78 | 0/79 | +1.3 |
Zero means no recorded label, not no business; multi-label cells overlap.

Recorded roles and delivery checks
Inspection systems must connect to process assessment
The Machine-vision inspection systems label covers 12 records (15.4% of this cohort). This archive clue raises a verification question about Inspection assessment or diagnosis for a defined process; it does not establish that these companies already deliver it.
