A method for manufacturing a plurality of optical devices comprising the steps of:-Providing a replication tool (1), the replication tool comprising a replication surface defining an array of replication cells, each replication cell comprising a lens replication portion (2) and a spacer replication portion (3), wherein the spacer replication portion on the replication tool is more indented than the lens replication portion,-Bringing the replication tool and a support (6) in contact with each other with replication material (11) between the replication surface and the support,-Causing the replication material to harden,-Wherein the lens replication sections are caused to be kept at a distance from the support when the support rests against the replication tool,-Removing the replication tool, and-Separating the hardened replication material into individual optical devices, each device having a replicated surface portion with a structure corresponding to a negative of a replication cell and comprising a spacer portion and a lens portion, wherein the lens portion is recessed with respect to the spacer portion. |
