Metrology Market Applications

While lens alignment and assembly has built a successful foundation for OATI, development of QuickPRO-3D™ Profiler has opened a vast new market for the company. Utilizing a chromatic confocal sensor for single point and line scan our profiler can quickly image surfaces from flat semiconductor wafers and MEMS to aspheric and freeform optics. QuickPRO-3D™ was designed to be the perfect fit for in-line production QA/QC requirements in applications like those mentioned below. If you don't see your application, give us a call so we can learn the specifics, or send us a sample of what you would like us to measure. We enjoy a challenge.

  • Measure tip/tilt of lens

  • Verify P-V and SAG

  • Identify deviation from the specified lens prescription.

  • Measure surface deviations in zone diameter, depth, and transition gap.

  • Identify localized slope errors.

  • Measure photo spacer location, dimensions and integrity.

  • Measure color filter volume for LC one-drop fill

  • Locate defects that cause Mura aberrations.

  • Identify foreign object contamination.

  • Inspect single point diamond turned (SPDT) mold geometry as pre-production QA

  • Measure micro-lens height and profile

  • Identify local punctures or other structural aberrations made by the forming process

  • Inspect line width and feature spacing

  • Scan for warpage

  • Measure via size, depth and position

  • Measure top and bottom surfaces of transparent films to identify any critical deviations in thickness

  • Use generated plots to pinpoint and implement process improvements to eliminate potential failure zones
