Optiques d’ultra-précision

UPMT's DPI® and CLAP™ proprietary technologies further push the limitations of micro optics mastering by achieving submicron position accuracy over the complete area of a large master, introducing new solutions for small series to large volume replication.

By combining ultra-precision 3-axis diamond turning and DPI®, arrays of freeform lenses can be machined onto replication masters or mold inserts. With DPI®, extremely low surface form error and roughness can be obtained on a large number of lenses such as required for imaging applications like future AR/VR products.

To demonstrate the performances of its patented DPI® technology for diamond turning of lens arrays, Wielandts UPMT has designed a fully populated master based on typical industry requirements in terms of lens sizes, number of lenses, master dimensions and tolerances for imaging applications.
