A comprehensive comparison of three silicon lens inspection technology routes: laser interferometry, white‑light interferometry, and confocal. From principles, speed, and accuracy to application scenarios – backed by 50,000‑part real‑world data.

How to assess a supplier's quality level when procuring microlenses? 5 key questions: inspection coverage, inspection equipment, measurement reports, defect handling, and third‑party verification – to quickly identify reliable suppliers.

As the scale of optical communication microlens wafer mass production continues to expand, what requirements does a target of100,000 microlenses per dayplace on inspection equipment? This article analyses the selection logic and key metrics for large‑scale production scenarios.I. The In

Automated full inspection of silicon wafer microlens arrays faces three major technical challenges in practical implementation:positioning recognition, batch efficiency, and data management.This article breaks down each challenge based on real‑world experience and provides practical sol

Why do microlens yields fluctuate? The root cause lies in tooling and consumables (70% of issues) and sub‑nanometre inspection provides the data‑driven closed‑loop solution for quality improvement.

Domestic laser interferometric 3D profilometers have achieved breakthroughs in (a)spherical lens mass‑production inspection: non‑scanning technology delivers ~1 sec/lens inspection speed, 0.5 nm resolution covers mainstream accuracy requirements, and localised service ensures production line deployment.
