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.
