The Shanghai International Optics Fair continues to be one of the leading international exhibitions for the optical industry, bringing together manufacturers, suppliers, and technology providers from across the global optical market.

This year, Rotlex participated in the exhibition and welcomed visitors to our booth N2B85, where we presented our advanced metrology technologies for ophthalmic lens manufacturing and quality control.

Showcasing the Full Lens Quality Control Process

At the Rotlex booth N2B85, visitors were introduced to the concept of the complete quality control cycle for optical lenses.

Rather than focusing on a single measurement point, Rotlex solutions are designed to support manufacturers across multiple stages of the production process, from lens manufacturing to final inspection.

During the exhibition, the booth presentation illustrated how measurement technologies support the inspection of:

  • Contact lenses throughout the full QA cycle

  • Spectacle lenses and optical components

  • Precision optical surfaces and molds

This approach reflects the growing need for reliable measurement solutions that help manufacturers maintain consistent optical performance while improving production efficiency.

Live Demonstrations and Industry Interest

Throughout the exhibition, the Rotlex team demonstrated measurement systems directly at booth N2B85, allowing visitors to see the technology in action.

Manufacturers and industry professionals stopped by to learn more about how advanced metrology systems can improve inspection workflows and support modern production environments.

These discussions highlighted the increasing demand for accurate, automated, and reliable optical measurement technologies.

Strengthening Connections in the Asian Optical Market

Participation in SIOF 2026 also provided an opportunity to reconnect with partners and meet new companies within the rapidly growing Asian optical market.

The exhibition continues to serve as an important platform for exchanging ideas, exploring new collaborations, and understanding the evolving needs of optical manufacturers.

Looking Forward

Rotlex remains committed to supporting the optical industry with advanced measurement solutions designed to improve quality control, efficiency, and reliability in lens manufacturing.

We would like to thank everyone who visited us at booth N2B85 during SIOF 2026, and we look forward to continuing the conversations that began in Shanghai.

Why Do Free-Form Progressive Lenses Fail Quality Control?

Why Do Free-Form Progressive Lenses Fail Quality Control?

Free-form progressive lenses fail quality control for a recognizable set of reasons: the produced surface deviates from the design file because of tool wear, material variation, thermal effects, or process drift; the corridor is mispositioned or has the wrong power progression; peripheral astigmatism exceeds design limits; localized defects such as optical islands or edge artifacts appear; or the lens is measured under conditions that make a conforming lens appear non-conforming.

What’s the Best Way to Map Optical Power Across a Progressive Lens?

The best way to map optical power across a progressive lens is full-surface wavefront sensing, which captures the complete power distribution in a single measurement rather than sampling isolated points.

Best IOL Measurement Solution: Building a Complete Capability

The best IOL measurement solution is not a single instrument but a coordinated capability covering the whole intraocular lens workflow: optical quality characterization for design and verification, model-eye measurement aligned with ISO 11979-2 configurations for regulatory-grade optical data, batch measurement for production throughput, and physical measurement of thickness and layer structure.

Virtual Cornea Addition Cannot Substitute for a Physical Cornea in IOL Wavefront Measurement: Evidence from Optical Simulation

Lens thickness measurement determines the thickness of a lens – at its center, its edge, or across its whole surface. For flexible lenses such as soft contact lenses, thickness must be measured with a non-contact optical method, because mechanical gauges compress the lens and produce artificially low readings.
