Leading Ophthalmic Lens Measurement Solution: What Defines One

A leading ophthalmic lens measurement solution covers the full range of ophthalmic lenses – spectacle, contact, and intraocular – with non-contact, full-surface measurement at the accuracy and speed each application demands. It maps optical power across complex freeform and progressive designs, measures physical parameters such as thickness and sagittal height to micron level, verifies optical […]
How Do I Verify a Progressive Lens Against Its Design File?

To verify a progressive lens against its design file, measure the produced lens with a full-surface power mapping system, load the intended design file, and let the system generate a difference map showing where the measured lens deviates from the design. The Rotlex FFV (Free-Form Verifier) performs this verification in about 4 seconds: it captures […]
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. Rotlex provides this as […]
