Smartphone cover glass defects — micro-scratches, pitting, edge chips, coating imperfections — are notoriously difficult to detect at production speed. Traditional 2D vision misses sub-micron defects that become visible only under specific viewing angles.
3D + AI solution
Our system combines SmartRay ECCO 3D sensors with Retina AI Vision to capture sub-micron depth profiles of the glass surface. The 3D scan reveals defects invisible to 2D cameras, while deep learning classifies them in real time at production speed.
Defect detection capability
- Micro-scratches — down to 5 micrometre width and depth
- Edge chips — corner damage, cover glass integrity
- Pitting — surface imperfections from glass forming
- Coating defects — anti-fingerprint, anti-reflective, oleophobic layer uniformity
- Bubble and inclusion detection — internal glass defects
Applications
Smartphone cover glass manufacturers, tablet and laptop display suppliers, wearable device glass producers, and optical component makers. Our systems inspect thousands of units per hour with near-perfect defect detection rates.
