Metroโ€‘Cell is built for batch-based, high-throughput inspection. It can analyze between 72 to 81 components per tray, with an average inspection time of approximately 50 seconds per part. This efficiency reduces manual intervention and enables consistent, fast-paced quality control directly on the production floor.
The Metroโ€‘Cell delivers highly precise measurements, with radius of curvature (ROC) accuracy better than ยฑ5โ€ฏยตm and center thickness accuracy within ยฑ2โ€ฏยตm. Repeatability is excellent, maintaining less than ยฑ2โ€ฏยตm variation in ROC and ยฑ1โ€ฏยตm in thickness, making it reliable even in large-scale production scenarios.
Yes, Metroโ€‘Cell supports a wide range of geometries, including symmetric and asymmetric lens buttons, male/female plastic molds, metal inserts, and even complex freeform designs. It uses adaptive scanning algorithms, which allow it to analyze parts without the need for custom fixtures or recalibration between different shapes.
Yes, the system is modular and designed to run alongside other QA or manufacturing equipment. It operates reliably in cleanroom environments, requires minimal physical footprint, and integrates smoothly into both centralized QA stations and distributed production workflows.
