Why spectacle lenses are hard — and how we solve it

Transparent, curved, and highly polished lenses pose unique challenges that require specialized solutions.

Transparency Challenges

Defects can vanish without the right light path. Specular reflections & AR coatings create glare that hides sleeks and stains.

  • Telecentric/collimated backlight for edge chips and silhouette
  • Cross-polarization kits to suppress reflections from AR/hard coats
  • Coaxial bright-field for coating pinholes/haze

Curvature & Power

Spherical/toric surfaces introduce refraction, changing apparent defect shape and position.

  • Custom machine vision design per SKU
  • Liquid lens for rapid autofocus across curvature
  • Reflection-aware defect segmentation

Microscopic Defects

Engravings & ink markings are faint, tiny, and easily worn. Edge micro-chips affect mounting and optics.

  • Detects <10 µm surface scratches and pits
  • OCR/OCV of etch/ink IDs and batch codes
  • Bevel geometry and edge radius measurement

Quality Certification

Every PASS lens receives a Digital Quality Certificate (DQC) with complete inspection records.

  • Annotated defect snapshots and measurements
  • Operator and station traceability
  • Optional lensometer readings integration

007 · FAQ

Frequently asked questions

Answers to common questions about our spectacle lens inspection solution.

Yes. Coaxial bright-field with cross-polarization suppresses glare and reveals pinholes, haze, and stains. Dark-field adds sensitivity to sleeks.
Yes. The system detects and measures engravings/ink marks, verifies fitting cross/PRP positions, corridor length, and mark spacing against the recipe.
We can integrate with an automated lensometer to capture sphere/cylinder/axis/prism and attach readings to the DQC.
Telecentric backlight metrology and dual-camera setups measure CT/ET and compute wedge angle with high repeatability.
Uniform dome lighting with colorimetry provides ΔE maps for tint uniformity; optional UV stimulus characterizes photochromic kinetics.
Yes. We offer post-edging stations to verify bevel chips, diameter, and geometry before assembly.
