What is it about?
We present an automated 4-axis ultraprecision machining technique for manufacturing an array of hexagonal Fresnel lenses in a single process, without having separated sections assembled as a single master mold.

Why is it important?
The time-consuming assembly of several mold inserts precisely has been a long-standing challenge by the optical industry. Hence, the proposed technique would aid to address this issue as it could precisely machine a monolithic mold insert in a single process, eliminating the needs of assembling.
Perspectives
The developed automated Guilloche machining technique brings new insights for the promising challenges to remove manufacturing barriers of machining freeform surfaces with complex curvatures.
