Patent ID: 8318057

Claim:
A method of making optical elements on a wafer level comprising: making a master including a plurality of optical elements on a substantially planar surface thereof; simultaneously imprinting a replica of said plurality of optical elements in an imprintable material by applying the substantially planar surface of the master to the imprintable material; providing a support substrate for the replica, the support substrate having first and second opposing parallel surfaces, the replica being on one of the first and second opposing parallel surfaces; hardening the imprintable material to form a hardened replica, the hardening including hardening only portions of the imprintable material corresponding to the optical elements, such that regions not having the plurality of optical elements thereon include unhardened imprintable material; removing the master from the hardened replica; removing imprintable material from regions not having the plurality of optical elements thereon to form cleared areas; and separating the support substrate through the first and second opposing parallel surfaces in the cleared areas to form individual optical elements, each individual optical element including the hardened replica and the support substrate.
