Abstract
A method of manufacturing a plurality of optical elements (140), the method comprising providing a first wafer (120) having hardened replication material forming optical elements (140) on a first side of the first wafer (120), providing a second wafer (121) having hardened replication material forming optical elements (140) on a first side of the second wafer (121), depositing liquid droplets (180) on the first side of the first wafer (120) between the optical elements (140) aligning the first side of the first wafer (120) with the first side of the second wafer (121), and bringing the two wafers (120, 121) together such that the liquid droplets (180) on the first side of the first wafer (120) adhere to the first side of the second wafer (121).
