Screen detection lens

Screen Detection Lens – High-resolution imaging optics designed for display panel inspection, featuring telecentric design, chromatic correction, and anti-glare coatings for pixel-level defect detection.

Category:

Engineered for Display Manufacturing QA
Specialized for detecting:

  • Pixel defects (dead/stuck subpixels)

  • Mura effects (backlight uniformity)

  • Touch sensor alignment (ITO pattern inspection)

Critical Performance Features
✔ Telecentric Optical Path

  • <0.1° angular error for distortion-free measurement

  • Eliminates perspective error in edge inspections

✔ 4K+ Resolution

  • Resolves up to 8μm pixel structures (supports 3000PPI displays)

  • MTF >80% at Nyquist frequency

✔ Anti-Reflective Coating

  • Multi-layer AR treatment (400-650nm)

  • Reduces flare from backlight sources

✔ Modular Filter System

  • Optional polarizers for OLED inspection

  • IR-cut filters for LCD backlight analysis
