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 

Freeform Surfaces

The quick-attach LAS-Profiler™ module offers an economical alternative to a stand-alone 3D profilometry tool


CalcuLens™ Vertex enables the LAS to make relevant distance measurements in optical assemblies. 

LED Wafers

CalcuLens™ ROC delivers accurate and repeatable Radius Of Curvature measurements of lens surfaces by utilizing the unique design of the LAS.

DMI inspection uses that think with the long snout and some fancy science to measure distances accurately.
