Optimax Metrology

High precision optical and mechanical metrology enables Optimax to adhere to tight tolerances and ensure customer satisfaction. Optimax has more than 100 highly trained opticians that measure and certify optics to customer supplied specifications. Following specific quality control standards, Optimax provides an inspection data record with each optic to ensure that it meets customer expectations.

Everyday Precision: Measurement Uncertainty

Often times an opticians ability to finish an optical surface is limited by metrology. Optimax has a continuous improvement program to identify measurement uncertainties and minimize their impact upon inspection of an optic. Conclusively measuring a lens attribute value to a known certainty establishes lens quality which creates value for the customer. Reliable inspection data removes unknowns in optical system modeling and performance.

State Of The Art: Stitching Interferometry

Optimax employs specialized tools to meet the most extreme metrology needs. Precision Standard Fizeau interferometers are used to measure irregularity for spherical and plano surfaces. For non-spherical surfaces such as aspheres, Optimax utilizes surface profilers, custom interferometer set ups, and stitching interferometers. Stitching interferometers measure multiple zones on the lens surface then stitch the data together mathematically to determine irregularity over the full aperture.

Please see our Asphere Metrology Matrix for more information.

Example measurement from a stitching interferometer

Optmax's new Metrology Laboratory will provide the best possible environment for precision measurements. The facility, with extreme vibration isolation and temperature control, is intended for measurement of high precision optical components to accuracies better than 50^th wave.

In addition, specialized software tools that measure irregularity for comparison to a Zernike fit specification are available to optical designers for measurement analysis.

Future Capabilities

Our R&D team is continuously working on independent projects and with the shop floor to improve our metrology capabilities. We are identifying and working to reduce the uncertainties in our measurements. In addition, our R&D team is working on software tools to better identify specific surface errors. We hope that this work can help our customers in specifying surfaces and our opticians in manufacturing surfaces.
