Abstract

MANUFACTURE OF OPTICAL ELEMENTS BY REPLICATION AND CORRESPONDING REPLICATION TOOLS AND OPTICAL DEVICES 5 A replication tool (10) for producing an optical structure comprising an optical element, is described. It comprises  a central section (c) having the shape defining a negative of a portion of the optical structure and a vertically aligned central axis (A);  a surrounding section (s) laterally surrounding the central section (c); and 10  one or more contact standoffs (15) defining a plane referred to as contact plane (5a). In a first azimuthal range, the surrounding portion provides a first compensation surface (f1) facing away from the central axis (A), and in a second azimuthal range, the surrounding portion provides a second compensation surface (f1) facing away from the 15 central axis (A). In any cross-section containing the central axis (A) in the second azimuthal range, a steepness of the second compensation surface (f2) is higher than a steepness of the first compensation surface (f1) in any cross-section containing the central axis (A) in the first azimuthal range. Corresponding optical devices and also a corresponding method for manufacturing an optical structure using the replication tool 20 (10) are described, too. The invention can be used for achieving a locally reduced footprint of the optical structure on a substrate (5) in wafer-level mass production. (Fig. 5)
